The incorrect statement about the nodal plane among the following is:
| 1. | A plane on which there is a zero probability of finding an electron. |
| 2. | A plane on which there is maximum probability that the electron will be found. |
| 3. | ψ2 is zero at nodal plane. |
| 4. | None of the above. |
The correct order of the total number of nodes of atomic orbitals is:
1. 4f > 6s > 5d
2. 6s > 5d > 4f
3. 4f > 5d > 6s
4. 5d > 4f > 6s
