What does it mean to say that an atom is in an excited state?

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.Aug 24, 2020

How does an excited atom return to its ground state?

  • If the photon has too much energy, the electron will cease to be bound to the atom, and the atom will become ionized. After excitation the atom may return to the ground state or a lower excited state, by emitting a photon with a characteristic energy.

What are the two ways an atom can be excited?

  • A hydrogen atom with excess energy is said to be “excited“. The two primary ways to excite an atom are through absorbing light and through collisions. When two atoms collide energy is exchanged. Sometimes, some of that energy is used to excite an electron from a lower energy level to a higher energy level.

How does an atom in the ground state become excited?

  • Electrons become excited when they absorb energy. In an atom, electrons prefer to stay in the orbitals closest to protons, known as the ground state. When given energy, electrons move to a higher energy level, known as an excited state.
