WebIonization energy is the amount of energy necessary to remove an electron from an atom. The ionization energy tends to increase from left to right across the periodic table because of the increase number of protons in the nucleus of the atom. It tends to decrease down a column of the periodic table because the number of electron shells is larger, making each … WebBefore we can see these trends, a quick chemistry recap might be good. First, metals react with nonmetals to form ionic compounds. The nonmetal atom takes one or more valence electrons from the metal atom. When an atom gains or loses a valence electron, it forms an ion. An ion with more protons than electrons is positively charged and called a ...
