What is excitement in chemistry?
The excited state describes an atom, ion or molecule with an electron in a higher than normal energy level than its ground state. The length of time a particle spends in the excited state before falling to a lower energy state varies.

What is meant by an excited atom?
Table of contents No headers An excited-state atom is an atom in which the total energy of the electrons can be lowered by transferring one or more electrons to different orbitals. That is, in an excited-state atom not all electrons are in the lowest possible energy levels.
