Activation Energy

Explanation:

Energy of Activation is the energy which must be provided to a chemical or nuclear system with potential reactants to result in: a chemical reaction.

More activation energy is required because it would take more energy to add elements across single bonds than it would take for double bonds.

ionization energy or ionisation energy, denoted Eᵢ, is the minimum amount of energy required to remove the most loosely bound electron, the valence electron, of an isolated neutral gaseous atom or molecule. This option is incorrect.

Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself. This option is incorrect.

NUclear energy is the energy released during nuclear fission or fusion, especially when used to generate electricity. This option is incorrect.
