प्रश्न
Ionisation Potential values depend on the nuclear pull. Explain.

उत्तर
The ionisation potential is the energy needed to remove an electron from a neutral isolated gaseous atom. The greater the nuclear charge, the stronger the attraction between valence electrons and the nucleus and the greater the energy needed to remove the electron(s).
