What is ground state and excited state of an electron?

Text Solution

Verified by Experts

When the electrons in ann atom are in their lowest (normal) energy state, they revolve in their respective orbits without losing energy. This state of the atom is called its ground state. When energy is supplied to an atom by subjecting it to electric discharge or high temperature, an electron in the atom may jump from its normal energy level (ground state) to some higher energy level, by absorbing a definite amount of energy. this state of the atom is called excited state.
