Bonds Flashcards
1
Q
ionic
A
metal and nonmetal
lose/gain
2
Q
covalent
A
non metals
water
3
Q
metallic
A
metals
sharing
lose becoming positive cations +ve charge
4
Q
non metals
A
gain becoming negative anions -ve charge
5
Q
atoms vs ions
A
atoms are neutral
ions are charged
6
Q
resonance binding, delocalised electrons
A
ozone, 03,
-dotted lines
7
Q
formal charge
A
electrons in valence - bonds to atom - unshared electrons in atom
-want number as low as possible
do lewis structure then calculation
