Question

What is successive ionization energy?

Answer 1

Ionization energy can be described as the amount of energy needed to remove the most loosely bound electron i.e. electron present in the outermost electron from an isolated gaseous atom of an element in its lowest energy state or also known by ground state to produce a cation is known as ionization potential.

Complete answer:
Ionization potential is an endothermic process which is generally expressed by the term I or I.P. and measured in electron volts. Energy removed to the first electron is called first ionization energy and to remove second electron it is termed as second ionization energy and so on in their respective manner.
The successive ionization energy can be defined as the energy required for the removal of the second electron from the ion which suggests that 1 mole of gas with 1st ion having +1 charge further gives +2 charge atom by losing one more electron from its shell. The successive energies are basically dependent on the number of electrons present in the atom. If there is only one electron present in the shell of an atom then successive energy is not possible as it is the energy required for the removal of the second electron from the ion.

Note:
Ionization energy gives us an idea about the reactivity of chemical compounds i.e. which compound is highly reactive and which one is least and it can also be used to determine the strength of chemical bonds. Ionization energy is measured by the units of electron volts or by kilojoule per mole.
