Lesson Summary. Energy levels inside an atom are the specific energies that electrons can have when occupying specific orbitals. Electrons can be excited to higher energy levels by absorbing energy from the surroundings. Light is emitted when an electron relaxes from a high energy state to a lower one.
The electron in a Hydrogen atom can only have certain energies. These energies are called the Hydrogen's âenergy levelsâ. The different energy levels of Hydrogen are denoted by the quantum number n where n varies from 1 for the ground state (the lowest energy level) to â, corresponding to unbound electrons.
