Question

The element sulphur had atom no 16 and mass no.32 calculate the no of protons,electrons,neutrons in it. give the arrangement of electronic configuration in energy shell. what is the valency of element?

Answer 1

no of electrons=No of protons=Atomic no=16
Mass no=protons+neutrons
neutrons=32-16=16

configuration- K  L  M
                       2  8   6
valency=2

Answer 2

protons=electrons=neutron = 16 Electronic configuration =2,8,6
valency =2
because it can give 2 electrons...
