Question

What would be the order of energies and wavelengths of photons emitted from different electronic transitions?

Answer 1

It has one electron attached to the nucleus. The energy in a hydrogen atom depends on the energy of the electron. When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level.

Answer 2

it has an electron that attached to a magnetism
