Question

In the main energy level, the orbital with more number of nodal planes will be of_________.

• A. higher energy
• B. lower energy
• C. either 1 or 2
• D. neither 1 nor 2

Answer 1

The correct option is A higher energy

As we go to higher energy levels, we get additional spherical nodal planes, and an increase in energy. Within same energy level, 2p orbital has higher energy than 2s, 3d has higher energy than 3p, which in turn has more energy than 3s orbital. More nodal planes means higher energy
