Expert Answer

Step 1

For Strontium,

 

Symbol of the element is .

Strontium is a ‘s’ block element.

Electronic configuration of strontium is:

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2

Step 2

For ‘s’ block element number of electrons in the outer shell will be the group  number, so for strontium 2 is the valence electron in the outer shell.

Group number is 2.

Strontium normally shows +2 oxidation state.

Electronic configuration of ion will be:

1s2 2s2 2p6 3s2 3p6 4s2 3d10
4p6
