ATOMIC MASS OF Z=ATOMIC MASS OF Y - ATOMIC MASS OF X=102-62=40.
THEREFORE, THE ELECTRONIC CONFIGURATION =2,8,18,8,4.
THE VALENCY IS 4 SINCE THE LAST SHELL WILL HAVE 4 VALENCED ELECTRONS.
THEREFORE, THE ATOMIC NUMBER OBTAINED WOULD BE THE VALENCY OF ELEMENT Z. (ANSWER).
THIS IS THE ONLY ANSWER AND DON'T TRY TO DELETE THIS AGAIN.
