Name two elements that you would expect to have chemical properties similar to Mg . What is the basis for your choice ?

Explanation

The two elements that have chemical properties similar to Mg and Be and Ca .
1 . Be Mg and Ca Belong to same group I.e., Group 2 (IIA) .
2 ) The Outermost shell of these three atoms consists of 2 electrons .
3 ) We know the physical and chemical properties of elements are related to their electrons configuration particularly the outer shell configuration .
4 ) These three elements Be , Mg , Ca have the outer shell configuration as `2s^(2) . 3s^(2) and 4s^(2) ` .
5 ) Hence we expect that Be and Ca have similar properties with Mg .
