a)State what are the similarities and differences between the hydrogen atom in 1s orbital and 2s orbital?

Question

b)Describe the average distance of electron in a 2s orbital from their nucleus
compared with electron in a 3s orbital.

Answer 1

1s and 2s are both spherical, but 2s has a bigger radius.
Similarly, 2s has a slightly smaller radius than 3s.

Answer 2

a) The similarity is that they both have a probability of being at the nucleus. The difference is that whereas the 2s has only one node in its radial wave, the 3s orbital has 2 nodes. b) Similarity: Both belong to the same energy level. Difference: The radial wavefunction of the 2s orbital has 1 node whereas the 2p orbital has none. On the other hand, the 2s orbital has no nodes on its angular wavefunction but the 2p has 1 node. c) The 3s.
