How does ionization energy affect bonding?
Elements that have lower ionization energies have a greater chance to form a cation, thereby having a greater tendency to form ionic bonds.
Ionization energy is the energy required to remove electrons from gaseous atoms or ions.
When forming an ionic bond, one atom must form a cation by losing one or more electrons.
In general, elements that have lower ionization energies have a greater chance to form a cation, thereby having a greater tendency to form ionic bonds.
Ionization energy decreases down a group in the periodic table due to the fact that the outermost electrons are further away from the nucleus. Ionization Energy decreases as you go left to right across a period and decreases as you go down a group.
The factor that affects the changes in ionization energy is the effective nuclear charge; if an atom has a smaller effective nuclear charge, they have a smaller ionization energy and vice versa.
