Lewis Structures - ANsWEr-represents the transfer or the sharing of electrons in
chemical bonds
octet rule - ANsWEr-EVERY ATOM WANTS 8 ELECTRONS IN THEIR OUTERSHELL
ionic bonding - ANsWEr-chemical bond formed through the transfer of one or more
electrons from one atom or group of atoms to another group
EX : NaBr
metals - ANsWEr-give
nonmetals - ANsWEr-take
oxidation number - ANsWEr-the superscript indicating the charge on an ion
ion - ANsWEr-atom with either positive or negative charge
binary compound - ANsWEr-compounds in which 2 elements are present , metal and
non metal - nonmetal changes to ide
ionization energy - ANsWEr-energy required to remove the most loosley held electron
from outer shell ; up and to the right
,polyatomic molecule - ANsWEr-nonmetals that form one ion
covalent bond - ANsWEr-sharing of electrons
EX : CO2
polyatomic ions - ANsWEr-Ag silver ion
Fe 2+ ferrous ion
Fe 3+ ferric ion
Cu 1+ cuprous ion
Cu 2+ cupric ion
binary molecule - ANsWEr-1st word : prefix and full name

bonding electrons - ANsWEr-pairs of valence electrons that are shared between pairs
non bonding electrons - ANsWEr-lone pairs that
are not involved in electron sharing
Linus Pauling - ANsWEr-Nobel prize Chemist
electronegativity - ANsWEr-measure of atoms attraction for electrons it shares with
another atom in a chemical bond
electronegativity increases - ANsWEr-left to right
electronegativity decreases - ANsWEr-top to bottom
repulsion - ANsWEr-gives molecule shape, describes distance b/w bonding and non
bonding pairs of electrons
molecular geometry - ANsWEr-3 dimensional arrangement of atom within a molecule
VSEPR - ANsWEr-valence shell electron pair repulsion theory - set of procedures for
predicting a 3 dimensional geometry molecule
