Philoid · Accepted Answer

In the case of 2s orbitals, the given charge cloud diagram (Fig 2.1) clearly shows a different probability density than 1s orbital. It can be seen that the probability density first decreases sharply to zero and again starts increasing.

And from the probability density graph :

We can conclude that after reaching small maxima it decreases again and approaches zero as the value of r increases further. The region where this probability density function reduces to zero are nodes which is 1 for 2s orbital which also can be seen in Fig 2.1.

hence, option (iv) The probability density of electrons for 2s orbital decreases uniformly as the distance from the nucleus increases is incorrect as the decrease of probability density does not occur uniformly.

Other 3 options (i) 1s and 2s orbitals are spherical in shape. (ii) The probability of finding the electron is maximum near the nucleus. (iii) The probability of finding the electron at a given distance is equal in all directions are all correct and they can be seen in Fig 2.1.
