Answer 2

The correct option is b.

• All 's' orbitals are spherical and they are spherically symmetrical.
• As the value of n increases the size of the 's' orbital also increases not decreases.
• Each 's' orbital has the n region of high probability.
• The number of nodes in ns orbital is equal to (n-1).
• Thus, the wrong statement is statement b.
