Web21 jan. 2024 · An ionic compound is made up of charged particles, called ions. It has a giant lattice structure with strong electrostatic forces of attraction. Part of Combined Science … Web16 aug. 2024 · Ionisation energy is governed by the charge on the nucleus, the amount of screening by the inner electrons, the distance between the outer electrons and the nucleus. As you go down the Group, the increase in nuclear charge is exactly offset by the increase in the number of inner electrons.
