CHEM 103 FINAL EXAM Qu estions and
an sw er s w ith accu r ate
r ationales(PASSED)
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
