<p>Ionization energy is the energy required to remove an electron from an atom or ion in the gaseous phase. The first ionization energy (IE₁) is the energy required to remove the first electron.</p> Signup and view all the answers

<p>IE increases going from left to right due increased nuclear charge, and decreases down a group due to increased distance of valence electrons from the nucleus and increased shielding by the inner shell electrons.</p> Signup and view all the answers
