Question

S-2 has complete;y filled with K,L and M shells Find its atomic
number

Mohit Gupta · Accepted Answer

As S-2 has completely filled K, L, M shell, therefore
the total number of electron present in S-2 is equal to
18
As the symbol suggest, sulphur has gained 2 electron Therefore
number of electron in sulphur atom is 16
As the atomic number is the number of proton in a neutral atom,
therefore number number of protons = 16 and hence its atomic number
is 16
