Question

What is ionization energy with example?

Answer 1

Ionization energies measure the tendency of a neutral atom to resist the loss of electrons. It takes a considerable amount of energy, for example, to remove an electron from a neutral fluorine atom to form a positively charged ion. F(g) F+(g) + e- Ho = 1681.0 kJ/mol.

Answer 2

Answer:

Ionization energy => Ionization energy is the energy required to remove the electron from its outermost shell...

i.e. The energy that we need to provide to the electron so that it will overcome the nuclear pull by the nucleus and will jump out of the outermost shell of the atom...

E.g =>

Na has configuration [Ne] 2s1

&

Mg has configuration [Ne] 2s2

Here the energy we need to provide so that the electron in 2s shell of Na is called Ionization energy....

Additional info =>

To compare the ionization energies of two atoms we see whose shell is more complete....

In above example ,

Mg has the complete 2s shell so it'll require more energy than Na....

So Mg has more ionization energy than Na....
