Question

what is mean of ionization energy​

Answer 1

Answer:

Explanation:

Alternatively, we can also state that ionization or ionisation energy is the measure of strength (attractive forces) by which an electron is held in a place.

Answer 2

Ionization energy:

      In physics and chemistry, ionization energy is the minimum amount of energy required to remove the most loosely bound electron of an isolated neutral gaseous atom or molecule.

                                  X(g) + energy → X+(g) +e-

      Ionization energy is positive for neutral atoms, which means that ionization is an endothermic process. Roughly, the closer the outermost electrons are to the nucleus of the atom, the higher the atom's ionization energy.

      It is expressed as the energy to ionize a mole of atoms or molecules, usually as kilojoules per mole(KJ/mol), kilocalories per mole(Kcal/mol).

Rules of coulombic attraction:

        1) Ionization energy generally increases from left to right within a given period.

        2) Ionization energy generally decreases from top to bottom in a given group.

The most notable influences that determine ionization energy includes;

• Electron configuration
• Nuclear charge
• Number of electron shells
• Effective nuclear charge
• Stability
