C3a                              What are Atoms Like?

What is an atom?



What is the structure of an atom?




•   Atoms are made up from a central ___________ that is orbited by __________

•   The nucleus is made up of ________________ and ____________________.

•   So, atoms are made up from 3 sub-atomic particles; ______________,

    _______________ and _____________________.



What are protons, neutrons and electrons?


    sub-atomic particle               charge                         mass
         protons
        neutrons
        electrons



IMPORTANT FACT

An atom always has an ____________ number of ________________ (+) and

________________ (-). This means that they have no overall charge – we say

that they are ______________________.



      How can we work out the number of protons, neutrons and electrons in an atom?
•   Each different type of atom is a different ______________ and has a

       different number of ____________, ____________ and ______________.



   •   Everything on Earth is made up from about _________ different elements and

       they are listed on the periodic table:




                                         23




Consider Sodium

Each element can be found in its own square. Find sodium and copy the information

into this box:
                                        What can we tell from this information?




       Na
        sodium




       Tasks
1. Using a periodic table, find the symbol and the atomic number for:

   a) Helium

   b) Potassium

   c) Iron

   d) Copper

   e) Bromine



   2. Complete the following table:

      Name                     Symbol             Atomic Number            Mass Number
     Lithium                     Li                     3                       7
     Carbon
     Calcium
    Aluminium
       Iron


   3. Now calculate the number of protons, neutrons and electrons in one atom of

      each element from the table above.


Remember:      Atomic number = number of protons (there must be an equal number of electrons)

               Mass number = number of protons + neutrons



  Name           Number of protons         Number of neutrons         Number of Electrons
 Lithium                3                       7-3 = 4                       3
 Carbon
 Calcium
Aluminium
   Iron


How are elements arranged in the Periodic Table?



            Find the following elements, in order, Hydrogen

                                                     Helium

                                                     Lithium
Beryllium

                                                Boron

                                                Carbon

                                                Fluorine

                                                Neon

                                                Sodium




What do you notice about the atomic numbers and atomic masses of these elements?

Give as much detail about any trends (patterns) that you spot. Answer in bullet points.
Scientists use isotopes to carbon-date dinosaur bones and other fossils.




                                              Isotopes
•   Isotopes are different varieties of the same element.

•   Isotopes have:

          the same __________________                   but       different _______________

    or    the same number of ___________                 but      different numbers of _______



•   Carbon is an element that has 2 isotopes called carbon-12 and carbon-14



                         Carbon-12                                            Carbon-14

                      12                                                      14



                      6    C                                                  6    C
Number of:

         protons     =

         neutrons     =

         electrons =



Important:

The neutrons do not affect the __________________________ of an element so

different _____________________ of an element perform EXACTLY THE SAME

chemical reactions they are just heavier.




         Task

Hydrogen has 3 isotopes. They have mass numbers of 1, 2 and 3. Calculate the number

of protons, neutrons and electrons for all 3 different isotopes of hydrogen.

    e) P2O5                                        j) CuSO4.5H2O




                               Electronic Structure


•   The electronic structure shows us how electrons are arranged in an atom.

•   Electrons occupy the space around the _______________.

•   Electrons ___________ the nucleus in _____________ (sometimes called

    energy levels).

•   Electrons must fill the ________ shell, which is closest to the nucleus before

    they can start to fill the _______ shell.

•   The 1st shell can hold a maximum of _____ electrons

    The 2nd shell can hold a maximum of _____ electrons

    The 3rd shell holds a maximum of _____ electrons before starting the 4th shell.



e.g. sodium has 11 electrons so the electronic arrangement for sodium is:



    Calcium has 20 electrons so the electronic arrangement for calcium is:

For your exam:
You must be able to deduce the electronic structure of the first 20

elements in the periodic table e.g. calcium is 2.8.8.2.

C3a Structure Of The Atom

  • 1. C3a What are Atoms Like? What is an atom? What is the structure of an atom? • Atoms are made up from a central ___________ that is orbited by __________ • The nucleus is made up of ________________ and ____________________. • So, atoms are made up from 3 sub-atomic particles; ______________, _______________ and _____________________. What are protons, neutrons and electrons? sub-atomic particle charge mass protons neutrons electrons IMPORTANT FACT An atom always has an ____________ number of ________________ (+) and ________________ (-). This means that they have no overall charge – we say that they are ______________________. How can we work out the number of protons, neutrons and electrons in an atom?
  • 2. Each different type of atom is a different ______________ and has a different number of ____________, ____________ and ______________. • Everything on Earth is made up from about _________ different elements and they are listed on the periodic table: 23 Consider Sodium Each element can be found in its own square. Find sodium and copy the information into this box: What can we tell from this information? Na sodium Tasks
  • 3. 1. Using a periodic table, find the symbol and the atomic number for: a) Helium b) Potassium c) Iron d) Copper e) Bromine 2. Complete the following table: Name Symbol Atomic Number Mass Number Lithium Li 3 7 Carbon Calcium Aluminium Iron 3. Now calculate the number of protons, neutrons and electrons in one atom of each element from the table above. Remember: Atomic number = number of protons (there must be an equal number of electrons) Mass number = number of protons + neutrons Name Number of protons Number of neutrons Number of Electrons Lithium 3 7-3 = 4 3 Carbon Calcium Aluminium Iron How are elements arranged in the Periodic Table? Find the following elements, in order, Hydrogen Helium Lithium
  • 4. Beryllium Boron Carbon Nitrogen Oxygen Fluorine Neon Sodium What do you notice about the atomic numbers and atomic masses of these elements? Give as much detail about any trends (patterns) that you spot. Answer in bullet points.
  • 5. Scientists use isotopes to carbon-date dinosaur bones and other fossils. Isotopes • Isotopes are different varieties of the same element. • Isotopes have: the same __________________ but different _______________ or the same number of ___________ but different numbers of _______ • Carbon is an element that has 2 isotopes called carbon-12 and carbon-14 Carbon-12 Carbon-14 12 14 6 C 6 C Number of: protons = neutrons = electrons = Important: The neutrons do not affect the __________________________ of an element so different _____________________ of an element perform EXACTLY THE SAME chemical reactions they are just heavier. Task Hydrogen has 3 isotopes. They have mass numbers of 1, 2 and 3. Calculate the number of protons, neutrons and electrons for all 3 different isotopes of hydrogen.
  • 6. Compounds • An element is a substance which: 1. 2. • A compound is a substance that contains at _____ or more _________ chemically bonded together. • You must be able to identify the elements in a compound from its formula, using a periodic table e.g. CuSO4 contains: _____ atom of the element copper, Cu _____ atom of the element sulphur, S _____ atoms of the element oxygen, O Task Identify which elements make up the following compounds and how many atoms of each element there are. The first one is done as an example (it continues on the next page. a) MgO f) C6H12O6 Mg Magnesium – 1 atom O Oxygen – 1 atom b) K2O g) Al2O3 c) CO2 h) Fe(OH)2
  • 7. d) NaOH i) KCr2O7.6H2O e) P2O5 j) CuSO4.5H2O Electronic Structure • The electronic structure shows us how electrons are arranged in an atom. • Electrons occupy the space around the _______________. • Electrons ___________ the nucleus in _____________ (sometimes called energy levels). • Electrons must fill the ________ shell, which is closest to the nucleus before they can start to fill the _______ shell. • The 1st shell can hold a maximum of _____ electrons The 2nd shell can hold a maximum of _____ electrons The 3rd shell holds a maximum of _____ electrons before starting the 4th shell. e.g. sodium has 11 electrons so the electronic arrangement for sodium is: Calcium has 20 electrons so the electronic arrangement for calcium is: For your exam:
  • 8. You must be able to deduce the electronic structure of the first 20 elements in the periodic table e.g. calcium is 2.8.8.2. Element Atomic Electronic Structure Group Number Number H 1 no number He 2 Li 3 Be 4 B 5 C 6 N 7 O 8 F 9 Ne 10 Na 11 Mg 12 Al 13 Si 14 P 15 S 16 Cl 17 Ar 18 K 19 Ca 20 What do pattern do you notice in the number of electrons in the outer shell and the group number of each element?
