ionization-potential

Noun

/ˌaɪənaɪˈzeɪʃən pəˈtɛnʃəl/

Definition

Ionization potential, also known as ionization energy, is the minimum energy required to remove an electron from an isolated gaseous atom or ion.

Examples

The ionization potential of hydrogen is about 1312 kJ/mol.
Different elements have varying ionization potentials, which influence their reactivity.
The trend in ionization potential can be observed in the periodic table as we move from left to right.

Meaning

It represents the energy needed to take away an electron from an atom, turning it into a positively charged ion. This process is fundamental in understanding atomic and molecular behavior in physics and chemistry.
