The probability density plots of 1s and 2s orbitals diagrams are given below :

  

The density of dots in a region represents the probability density of finding electrons in the region.

On the basis of the above diagram which of the following statements is incorrect?

1. 1s and 2s orbitals are spherical in shape
2. The probability of finding the electron is maximum near the nucleus
3. The probability of finding the electron at a given distance is equal in all directions
4. The probability density of electrons for 2s orbital decreases uniformly as the distance from the nucleus increases
