M = molarity

Question 8

Nuclei above the band of stability are likely to undergo

Answer 8

Beta emission

Because lowers the neutron - pronton ratio

Question 9

Nuclei below the band of stability are likely to undergo

Answer 9

Positron emission or electron capture because increases neutron proton ratio
