Anonymous: and may I give you a suggestion

sru8: what is it

Anonymous: Because your marks get deducted

sru8: but we do write elements first then their symbols then their valency then comes the formula

sru8: unless the marks are not given

Anonymous: If it is given to be X ..take it as X only

Hey buddy....

The atomic no. of X is 20 so it has 2 atoms in k-shell, 8 atoms in l-shell, 8 atoms in M- shell and 2 atoms in N- shell. It's valency is +2, therefore it's position in the periodic table in groups is 2.
We know X has valency +2 and Y has valency -2, therefore the reaction taking place will be XY.

Hope this helps...
