1. Ions

2. Ions are charged particles
The charge on an ion is the DIFFERENCE between the p+ and e-
Chloride ion
General term for negative ion = Anion

3. General term for positive ion = Cation

5. Ions form because atoms want to have a full valence shell (outer energy level).
like the nearest noble gas.
They will do this the easiest way possible.

6. Valence Electrons Number of electrons in the outer shell of an atom
Full outer shell
One or two

7. Bromine? Potassium? Oxygen? Aluminum?
How do the following form ions, and what’s their notation?
Remember this?
p+? no? e-?
Bromine? Potassium? Oxygen? Aluminum?

8. Ions vs. Atoms (and their isotopes)
