The attraction of each electron in an atom is unique. This is due to the charge on the nucleus, the distance and repulsion by other electrons.
IONIZATION ENERGY. The work required to remove an electron for an atom. No two electrons in an atom have the same value. This increases at certain stages leading to the energy shell model of the atom. ELECTRO NEGATIVITY. This is the number describing a particle's ability to retain an electron in a chemical reaction. It describes and predicts the degree of polarity of a chemical bond. ACTIVITY SERIES. The ability of atoms to hold onto their electrons is also expressed in the activity series of the elements. The concepts of electron transfer and voltage production in cells are explored at their simplest levels.
