Write Chemical Formula about this substance
Atoms gain or lose
Formation of Ions from Metals
Ions from Nonmetal Ions
Some Typical Ions with Positive Charges (Cations)

6. 
a bond is a force of attraction between two atoms

Ionic bond between atoms of metals and
nonmetals


Bonds that are formed by transfer of electrons
from one element to the other.

Produce charged ions all states. Conductors and
have high melting point.

Examples; NaCl, CaCl2, K2O

7. 
generally occurs in compounds of metals and
non-metals .

It is the result of the attraction of oppositely
charged ions.

The structures formed are very orderly and are
given the name crystal lattice.

Ionic solids are called crystals.

8. 
No sharing of electrons occurs between the
ions in the crystal lattice.

As a result, ionic solids are brittle.

Ionic solids conduct electricity only in the
molten state, and not very well.

Ionic solids are characterized by very high
melting and boiling points.

9. 


Ionic bonds are much stronger if the ions
have a large charge.
Ionic solids do not conduct electric current
because the ions are held together in a rigid
structure.
Ionic substances that are dissolved in water
are good conductors because the charged
ions are free to move in the solution.

10. 
Ionic bonds have an electronegativity
difference between 1.7 and 3.3

A representation of the kinds and number of
atoms in a substance.
A chemical formula that shows the lowest
whole number ratio of the atoms (ions) in
an ionic compound.
Example: KCl,
Mg Cl2

19. 
Atoms gain or lose electrons to arrive at a full set
of valence electrons.

When atoms gain or lose electrons they become
ions.

Ions are attracted to ions of opposite charge and
repelled by ions of the same charge.


This type of bonding is called ionic bonding

Atoms become ionic by losing or gaining electrons
from the atom it is bonding with

20. • The electrical force of attraction between
oppositely charged ions.
For Example:
Na+
F−

21. 


Ionic compounds result when metals react
with nonmetals
Metals lose electrons to match the number of
valence electrons of their nearest noble gas
Positive ions form when the number of
electrons are less than the number of protons

27. Ionic Bonds: One Big Greedy Thief Dog!

31. In ionic compounds, nonmetals in 15, 16,
and 17 gain electrons from metals
Nonmetal add electrons to achieve the
octet arrangement
Nonmetal ionic charge:

34. 1). Ionic bond – electron from Na is transferred to Cl, this causes a
charge imbalance in each atom. The Na becomes (Na+) and the Cl
becomes (Cl-), charged particles or ions.
