Question

(ii) If Z= 16, what would be the number of protons, number of neutrons and number of electrons
present in the element? Also, name the element.​

Answer 1

Answer:

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.

Solution :

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.
