Question

has lower
than
natting up of orbitals with electrons. The
principle states in the ground state of the
atoms, the orbitals are alled in order of
helt increasing energies. In other words
lectrons first occupy the lowest energy orbital
vatlable to them and enter into higher energy
rbitals only after the lower energy orbitals
w
Te filled.
The order in which the energies of the
bitals increase and hence the order in which
ne orbitals are filled is as follows:
s. 2s 2p 3s 3p, 4s, 3d, 4p, 5s, 4d. 5p. 47
1. 6p. 7s...
The order may be remembered by using
e method given in Fig. 2.17. Starting from
e top, the direction of the arrows gives the
der of filling of orbitals, that is starting from
ght top to bottom left.​
