The measure of the attraction that an atom has for electrons involved in chemical bonds is known as: ? electron affinity / radioactivity / ionization energy/ electronegativity

The answer is the last option. Electronegativity is the measure of the attraction that an atom has for electrons involved in chemical bonds.  It relates to covalent bonds where electrons are shared. The Pauling scale is the most used.

Yes i think so not 100 percent sure though
