Question

As number of shells increases, atomic orbitals become smaller and more stable.

• A. True
• B. False

Answer 1

The correct option is B False

As the number of shell increases, atomic orbitals size increases, and energy also increases.

As energy increases stability decreases

The arrangements of the subshells in increasing order of energy can be given as follow:

$1s<2s=2p<3s=3p=3d<4s=4p=4d=4f$
