1. Ionic Compounds Metal Non-metal Magnesium-12 8 (+) 10 (-) -2 Charge

2. Ionic Compounds Attraction between + ions and - ions
Electrons go from metals to nonmetals
electrons transfer from metal  to nonmetal
Yielding: cation+ & anion–
Electrons lost = Electrons gained

3. Metals Non-Metals steal electrons from metals
They then attract because their charges are opposite.
Metals

4. Naming monatomic Ions Metal Cations (+ charge):
For metals in groups IA, IIA and Aluminum
They have a charge that doesn’t change (1+, 2+ &3+)
Since the charge is constant, just knowing the element is enough to name them.
Name the metal, then put ion
Na+ Sodium ion
Sr2+ Strontium ion
Al3+ Aluminum ion

5. Naming monatomic Ions Metal Cations (+charge)
The other metals in the periodic table are called transition metals, and can generally have more than 1 charge (more on why later this year)
The charge needs to be included in the name
We do this by using roman numerals Metal(charge) ion
Fe3+ Iron(III) ion,
Cu2+ Copper(II) ion

6. Names of Variable Ions
Use a roman number after the name of a metal that forms two or more ions
Transition metals
(Fe3+) iron(III) ion
(Cu+ ) copper(I) ion
(Sn4+) tin(IV) ion
(Pb2+) lead(II) ion
(Fe2+) iron(II) ion

7. -1 +1 -2 +3 -3 +2
Transition Metals
have variable charges

8. Naming monatomic ions Anions (- charge)
Non-metals which are involved in ionic bonding have fixed charges
To name their ions we add –ide to the end of the element name
O2- Oxide
F- Fluoride
N3- Nitride

9. Negative Ions (single atoms)-3 -2 -1
Most of the negative ions have a set negative charge

10. Naming Binary Ionic Compounds
Contain 2 different elements
Name the metal first, then the nonmetal as -ide.
Use name of a metal with a fixed charge
Groups 1A, 2A, Al
Examples:
NaCl sodium chloride
MgI2 magnesium iodide
Al2O3 aluminum oxide
