4
Q
5 characteristics of covalent bonds
A
- shares e
- non metal & non metal
- forms molecule
- very strong bonds
- normally forms liquid and gasses at room temp
5
Q
5 characteristics of ionic bonding
END
A
- metals & non metals
- forms crystal structure ( formula unit )
- relatively strong bonds
- normally forms solids @ room temp
- valence e lost by metals & gained by non metals
END > 1.9

Q
6 characteristics of metallic bonds
A
- metals react with each other
- valence e form sea of delocalized e
- core e form a positive kernel which remains closely packed together
- e that move around freely give metal their conductibility
- very strong bonds
- mostly forms solids
