Valence electrons are generally the electrons located in the outermost shell of an atom and can be gained or lost in a reaction. As expected by periodic trends, it is less electronegative than its predecessor in the group, scandium, and less electronegative than the next member of period 5, zirconium; additionally, it is more electronegative than lanthanum, but less electronegative than lutetium due to the lanthanide contraction. The ground state electron configuration of ground state gaseous neutral yttrium is [ Kr ]. Electron configurations can also predict stability. There is some variation in the chemical properties of the lanthanides because of the lanthanide contraction and the hybridization, or mixing, of the 4f electrons with the valence electrons.
