Question
Discuss the similarities and differences between 1s and 2s-orbitals.
✓

Answer

The similarities in 1s and 2s-orbitals are as follows:

  1. Both have spherical shape.
  2. Both have the same angular momentum.

The difference in between them are as follows:

  1. Size of 2s-orbital is larger than that of 1s-orbital.
  2. Energy of 2s-orbital is greater than that of 1s-orbital.
  3. 2s-orbital has one node while 1s-orbital has no node.
