Question

Does 2s and 2p have the same energy?

Answer 1

Answer:

It is given that "In a hydrogen atom, the 2s and 2p orbitals have the same energy. however, in a boron atom, the 2s orbital has lower energy than the 2p". It is a fact that the energy of 2 p orbital is slightly more than the 2s orbital that illustrates the easy filling of electrons in the latter orbital...
