Question

explain the term ionisation energy​

Answer 1

Answer:

energy required to form an ion is called ionisation energy

Answer 2

Explanation:

Ionisation Energy- It is the minimum energy which is required to remove the outermost bonded shell electron from an isolated gaseous atom to ground state.

* Term isolation means absence of bonding to other atom.

* Ionisation energy is also known as I ionisation potential.

* Ionisation energy is also known as I ionisation enthalpy.

* In solid state electrons can never be removed.

* Ionisation energy is measured in electron volt/atom or eV/atom.

* It will be always an endothermic process means means the difference of heat will always be positive.
