What is the term for the energy released when an atom gains an electron?
When an electron gains energy it is considered to be in an excited state. At that point the electron jumps out to a level that is further from the nucleus of the atom. the further out the electron the more higher energy the electron has. Once it jumps out a level it then LOSES the extra energy and falls back to its original level, and in doing so emits a photon of light. Depending on…
When an electron absorbs a photon of light, it gains energy. This is quantized. When an electron gains energy, it moves to a higher energy level. Thus giving the equation hf=mcv. Therefore, as more energy is given to the electron, it gets 'excited' and maintains the energy by moving to a higher energy leve.
An atom is called an ion, when the atom either gains or loses an electron from its electron arrangement/structure. Their are two types of ions: A positive ion, is when an electron is lost from an electron arrangement/structure. A negative ion is when an atom gains an electron, into its electron arrangement/structure.
chlorine is a group seven element with outmost energy level lacking only one electron, thus is not stable. when it gains this electron, it gets an octet electron structure(8 e in the vallency shell) this makes it very stable in the enviroment; the reason why chlorine molecule exists due to its stable atoms but chlorine atom does not exist in nature
