sru8:
thanks for correcting me..
and may I give you a suggestion
what is it
Never write the name of element unless asked
Because your marks get deducted
but we do write elements first then their symbols then their valency then comes the formula
unless the marks are not given
If it is given to be X ..take it as X only
Ok
ok ok thank you

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...
