The element sulphur has atomic number 16...

The element sulphur has atomic number 16 and mass number 32 state the number of protons electrons and neutons in it. Give the arrangement of the elctons in different energy shells. What is the valency of the element?

Text Solution

Verified by Experts

No of protons =Atomic number =16 ltrbgt No of electons = No of protons =16
No of neutons = Mass no -no of protons
=32-16=16 ltrblt Electonic arrangement =K(2),L(8),M(6)
Valency of the element =8-6=2
