which periodic trend quantifies the amount of energy required to remove an electron from a neutral, gaseous atom? a) atomic radi
ahrayia [7]

Ionization energy is the energy needed to remove one electron from an atom in the gaseous state.

Ionization energy (IE) is the force needed to ionize a neutral atom or cation when it is in its gaseous state. Ionization potential is another name for IE. Ionization energy is conceptually defined as an element's affinity for its outermost electron (an electron it already has in its valence shell).

The least amount of energy needed to ionize an atom is needed to remove an electron from its ground state. Across the periodic table, there is a regular increase in ionization energy from top to bottom and left to right.
