Ionic bonds occur between these two types of elements
Metals and nonmetals
Covalent compounds are also called
Molecules
Sodium chloride, NaCl
It's ionic
What's the formula for magnesium chloride?
MgCl2
This group has 6 valence electrons and will make a 2- charge
Group 16
In this type of bonding electrons are not transferred, but rather...
shared
Magnesium sulfate, MgSO4
It's ionic!
This rule states that all elements are most stable with a complete outer electron shell.
The octet rule
The name of this polyatomic ion
PO33-
Phosphite
Each bond ____ represents how many shared electrons
2
Phosphorous trichloride, PCl3
It's covalent!
This is the number of valence electrons that fill the 1st (smallest) energy level
2 valence electrons

It's ionic!
This is a shortcut for determining how many valence electrons a group has.
Look @ the group number (the ones place example group 16 has 6 valence electrons)
