What is ionization energy and can you give an example of it? relate atomic size to ionization energy.

The necessary energy that we must contribute to a neutral atom in the gas phase to release an electron. The plucked electron will be the outermost and will require less energy since it is far from the nucleus.

Explanation:

The ionization energy increases in the periods of the periodic table and decreases in the groups. If the atom is very small, we will need a lot of energy to release the electron, while if the atom is larger the energy will be greater.

the answer is 303.15 or 303
