5 1.1 Matter Powerpoint Part A Classification Of Matter

2. MATTER AND ENERGY Dark matter, matter we cannot see. Perhaps it doesn’t have or emit light. Scientists look at galaxy clusters and determine the amount of gravity holding the cluster together. From this information they can determine mass. They find there is a great deal more mass than they can account for from the visible material, thus the proposed existence of a “new” kind of matter, dark matter.

6. IS AIR MATTER? Does air have mass? Does air have volume? YES, to both, so air is matter

8. THE BASIC UNIT OF MATTER IS AN ATOM There are over 118 varieties of atoms PERIODIC TABLE http:// www.webelements.com /scandium/
9. ELEMENTS contain only one type of atom. Ex: hydrogen (H) is an element that contains only hydrogen atoms, carbon (C) contains only carbon atoms, oxygen (O) contains only oxygen atoms, etc. Atoms of elements can combine together to form compounds. COMPOUNDS are neutral groups of atoms held together by chemical bonds. Ex: CO 2 , H 2 O, H 2 , O 2

12. ELEMENTS MONATOMIC ELEMENTS DIATOMIC ELEMENTS ALLOTROPES Atomic nitrogen N Molecular nitrogen N 2 Ozone O3 Atomic hydrogen H Molecular hydrogen H 2 Graphite, buckyball Atomic oxygen O Molecular oxygen O 2 Carbon C ALLOTROPE-different forms of an element in same physical state

14. ELEMENTS TO COMPOUND COMBINED WITH… Will Form… Sodium, Na, is a soft, shiny metal that can be cut with a butter knife. When in contact with moisture it will “explode”. Chlorine gas, Cl 2 , which is a green, poisonous gas once used as a chemical weapon in military operations.
15. Sodium metal and chlorine gas, under the right conditions, undergo a chemical change and combine to become….. 2 Na (s) + Cl 2(g) 2 NaCl The final compound has properties different from the elements that formed it. TABLE SALT!

17. MATTER NOW LETS DISCOVER MATTER AS MIXTURES THUS FAR WE HAVE REVIEWED MATTER AS PURE SUBSTANCES. PURE SUBSTANCE ELEMENT COMPOUND Carbon (C) H 2 O MIXTURE ?
24. Mixtures Summary Ex. salt-water solution, tea, Cool-Aid drink Ex.: salt & pepper mix, rocks, cereal, bag of assorted candy Not as easily separated Can be easily separated Individual components can not be easily seen Individual components can be easily seen Properties of combined components are usually different than those of each component Individual components retain their own properties Evenly mixed Not evenly mixed Homogeneous Mixture Heterogeneous Mixture

28. Classifying Matter Matter Pure Substances Mixtures Elements Compounds Homogeneous Heterogeneous He, O H 2 O, NaCl Tea, kool-aid Rocky Road ice cream, muddy water Review: How matter is classified
29. Classify the following substances as: Pure substance, heterogeneous mixture, or homogeneous mixture Return to index More review Gatorade Homogenous mixture Fruit Loops Heterogeneous mixture Pure substance Gasoline Dirt Heterogeneous mixture Sugar Crystals Pure Substance Air Homogeneous mixture Granite Heterogeneous mixture
Notas do Editor
Dark matter, matter we cannot see. Perhaps doesn’t have or emit light. Scientists look at galaxy clusters and determine the amount of gravity holding cluster together. From this information they can determine mass. They find there is a great deal more mass than they can account for of the visible material. Maintain there is dark matter that we cannot see or yet detect. Think it might be nuetrinos or baryonic particles.
