Question

What is the correlation between ionisation energies and reactivity of elements?

Accepted Answer

Ionisation energy is defined as the energy required for the removal of an electron from the outermost shell of an isolated gaseous atom. It is also known as ionisation potential. Reactivity of an element is defined as its activity or capacity to part in a reaction and form molecules. The reactivity of a cation depends upon the ease of removal of an electron from an atom. As electrons are present in nucleus attraction so, we require some input of energy to remove an electron from the outermost shell and this is known as ionisation energy. The ease of removal of an electron depends upon the size and effective nuclear charge of an atom. An atom having a large size will have a large distance between the nucleus and outermost shell. So, the outermost electron will be loosely bound. We require a small amount of energy to remove the electron and practically it is easy and possible to provide a low amount of energy. So, low ionisation energy means an atom loses electrons even at low temperature and form cation and reacts with an anion to give a molecule mans the atom has high reactivity.
Therefore, ionisation energy is inversely proportional to the reactivity. Low ionisation energy means higher activity. High ionisation energy means low reactivity.
