Explanation: just took the quiz
Believe it’s B alpha decay
Answer:
Reduction:
2e- + 2k+ ➡️ 2k
2e- + pb2+ ➡️pb
2e- +2H+ ➡️H2(diatomic molecule)
Oxidation :
2cl- ➡️cl2 + 2e- (Cl is a diatomic molecule)
2O-2➡️ O2+4e- (also diatomic molecule)
2Br-➡️ Br2 + 2e- (Br is also a diatomic molecule)

Sodium would form Na+
Oxygen would form O-2
Phosphorus would form -3 or +5
Sodium and oxygen would combine to form ionic bonds because one is a metal and the other is non-metal, while Phosporus and oxygen would combine to form covalent bonds because they are both non-metals.
