Solution

The correct option is A 2s
The probability density is maximum at the nucleus hence it must be a s orbital. Also it has one node. Hence it is a 2s orbital.

Question 03

The probability density plots of 1s and 2s orbital are given in figure.

The density of dots in region represents the probability density of finding electrons in the region. On the basis of above diagram which of the following statements is incorrect ?

(a) 1s and 2s orbitals are spherical in shape

(b) The probability of finding electron is maximum near the nucleus

(c) The probability of finding the electron at a given distance is equal in all directions

(d) The probability density of electrons for 2s orbital decreases uniformly as distance from the nucleus increases

Q. Assertion: The plots of the probability density and the radial probability function versus distance

r

from the nucleus for any particular orbital are not identical.

Reason: Probability density is

ψ^{2}

whereas radial probability function represents the probability of finding electrons in a shell of thickness

d r

.

The above graph represents a radial probability curve for an orbital. The number of radial nodes in the orbital is:
