Questions and Correct Answers Graded A+ And
Brand New
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
