Valence electrons are those electrons that are capable of participating in the formation of chemical bonds with other atoms. Near the bandedges the electrons can be described by simple effective mass pictures, i.e., the electrons behave as if they are in free space except their masses are m*. the Valence electrons 5f14 6d10 7s2 7p5, electrons in Earth's Crust, Oceans and Human Body. More info. LASC Rule XIX; Resources. Earlier in this activity it was mentioned that the electrons provide the properties of a given atom. Valence electrons get their name from their location within an atom. In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule when an electron is added to the atom to form a negative ion.
