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
Correct statement among the following is:
1. Number of angular nodes = n - l - 1
2. Number of radial nodes = l
3. Total number of nodes = n -1
4. All of the above
Maximum number of total nodes is present in:
1. 5s
2. 5p
3. 5d
4. All have same number of nodes
Orbitals having two spherical nodes are:
1. | 2s | 2. | 4s |
3. | 3d | 4. | 6f |
