plz mark me as brain list

Answer 2

Answer:

Ca2 is more stable than Ca because the Calcium ion has 20 electrons and is therefore more stable than Calcium which has only 18 electrons, while 18 electrons is less stable than 20 electrons.

20 (Ca2) > 18 (Ca) = more stable

18 (Ca) < 20 (Ca2) = less stable
