name the three types of chemical bond
ionic, covalent and metallic
1 of 18
describe ionic bonding
particles arre oppositely charged ions that attract
2 of 18
describe covalent bonding
particles are atoms which shares pairs of electrons
3 of 18
describe metallic bonding?
metal atoms share delocalised elctrons
4 of 18
where does covalent bonding usually happen?
non-metallic elements and compounds

where does metallic bonding usuallly happen?
metallic elements and alloys
6 of 18
when a metal reacts with a non-metal during ionic bonding what happens to the electron on the outer shell of the metal
the electrons are transfered
7 of 18
when metal atoms lose electrons what charge does the ion become?
they become postively charged ions
