Question
The probability density plots of 1s and 2s orbitals are given in Figure:
The density of dots in a region represents the probability density of finding electrons in the region.
On the basis of above diagram which of the following statements is incorrect?
Options
1s and 2s orbitals are spherical in shape.
The probability of finding the electron is maximum near the nucleus.
The probability of finding the electron at a given distance is equal in all directions.
The probability density of electrons for 2s orbital decreases uniformly as distance from the nucleus increases.

Solution
The probability density of electrons for 2s orbital decreases uniformly as distance from the nucleus increases.
Explanation:
As per the probability density curve, the probability of finding the electrons at the 1s orbital decreases as we move far from the nucleus, however in case of 2s the probability decreases initially then it increases with the distance and thereafter at a certain point it starts decreasing with the distance.
