Answer to Problem 2.10P

Electronic configuration of tungsten is:

  74=1s22s22p63s23p64s23d104p65s24d105p66s24f145d4

Explanation of Solution

Electrons are distributed in the orbitals of the sub-shell. The specific region of space in which the movements of electrons are confined is said to be shells which are divided into sub-shells and are s-, p-, d-, and f-. Among these sub-shells, the electrons are grouped as orbitals.

The numbers of electrons that these sub-shells can hold are:

s-block - 2

p-block - 6

d-block - 10

f-block - 14

The increasing order of energy of shells, sub-shell is:
