This means that after becoming excited and moving to a higher energy level, they soon fall back to their original energy level. What happens after an electron becomes excited?Įlectrons don’t like being in an excited state. When an electron absorbs energy, is it promoted to a higher energy level further away from the nucleus of the atom and is described as being ‘ excited’. This means that the energy absorbed by the electron must be exactly the same as the energy difference between the two levels. For an electron to move from a lower energy level to a higher energy level, it must absorb a set amount of energy because energy levels are quantised. The lowest energy level that an electron can be in is called the ground state. This is why objects have different colours – different materials’ electrons will vibrate at different rates, and therefore absorb different frequencies of light.Įlectrons can only exist in discrete energy levels (these can also be called electron shells) – they can’t exist halfway between. If a wave of light hits a material in which the electrons are vibrating at the same frequency as the wave of light, the electrons will absorb the energy and convert it into vibrational motion. In an atom, electrons vibrate at a specific frequency – this is called the natural frequency. Light absorption is the process in which light is absorbed by matter and converted into energy. Absorption and emission spectroscopy are two methods used to study.Electrons don’t like being in an excited state, and so fall back to their original energy level very quickly – they release a packet of energy called a photon when they do this.When electrons absorb energy, they become ‘excited’ and move to higher energy levels which are further away from the nucleus.Light absorption is the process in which light is absorbed and converted into energy. ![]()
