what is covalent bonding?
this is how 2 non metals atoms bond. they share electrons in their outershells become full
1 of 16
what is ionic bonding?
ionic bonding is when an atom loses or gains an electron. it is a bond between a metal and non metal.
2 of 16
what is metalic bonding?
each atom gives away electrons and forms possitive ions. electrons move around in a cloud
3 of 16
what is oxidation?
reaction where oxygen is added
4 of 16
name elemonts from highest reaction to lowest
potassium, sodium, calcium, magnesium, zinc, iron, copper, silver and gold
5 of 16
acid + alkali -->
a salt + water
6 of 16
name the ph of acid, neutral and alkali
acid: ph1 neutral:ph7. alkali:ph 14

what are half equations?
show what happens at one end or the electrode during electrolosis
11 of 16
what are negative ions?
they are netrual atoms that lose electrons at a positive electrode and oxidised
12 of 16
current =
current= change x time
13 of 16
what is a current?
the flow of electrisity through a circuit measured in amps
14 of 16
what is voltage?
the amount of push that electrons have measured in volts
