This type of Chemical bond "transfers electrons" to create ions
What is an Ionic Bond
This is the name of atoms that have had electrons added or subtracted
What are ions
Cation = positive
Anion = Negative

700.70
What is 5 sig. figs
Sandwich rule
final zero rule
This group does not participate in electronegativity. It is a royal pain
Who are the Noble Gases
This is the name of an atom with the gain or loss of neutrons
What is an isoptope
This is the name when solid, liquid, and gas exist simultaneously
What is triple point
This kind of chemical bonds holds together most polyatomic ions
What is a Covalent Bond

What is 44 g/molecule
C = 12
O = 16 X2
Equals 44
Periodicity is why we have the Periodic Table.
This man is concidered the "Father of the Periodic Table"
