The atomic number and mass number of an element are 16 and 32 respectively.Find the number of proton electrons and neutrons in it. State its valency .Is this element a metal or a non-metal .Justify your answer.

Explanation

No of protons =Atomic number =16
No of electrons = Atomic number = 16
No of neutrons = Mass number -Atomic number = 32-16=16 ltbrltgt Electronic configuration of the element =2,8,6
Valency of the element =(8-6)=2
The element is a non -kmetal sicne it tends to gain electrons and not lose electrons.
