To demonstrate that while acids and metals have similar group properties, they may differ in chemical reactivity. One factor that influences their chemical reactivity is called ionization energy. Ionization energy is the energy that is needed to remove one electron from the electron cloud of the atom while in the gaseous state. When ionized, the atom becomes a positively charged particle called an ion.
Several factors influence the amount of energy needed to remove an electron from an atom.
Sublevel filling- more ionization energy is needed to remove electrons from filled or half filled energy sublevels. Shielding effect-a lower ionization energy is involved when greater number of electrons lie between the nucleus and the outer electrons. Knowledge of compatibility or noncompatibility is essential to avoiding mishaps. Most of these compounds and their solutions are poisonous. Beware of skin contact.
