WebApr 15, 2015 · From what I understand, in a stepwise ionization process, it is always the highest-energy electron (the one bound least tightly) that is removed first. So when we go more to the right in the periodic table, there are more electrons, and thus much more possibility for these to shield the outer electron from attraction to the nucleus. WebThe first ionization energy would be the energy required to remove the first electron, the second ionization energy would be the energy to remove the second electron, and so on. The reason it's called ionization is that when you remove an electron from a neutral atom, it becomes a positively charged ion, or cation, having lost a negatively ...
WebThe first ionization energy of element A is defined as the energy required by an atom to form A + ions. The unit of ionization energy is given as KJ mol -1. A (g) → A + (g) + e – In the same way, second ionization energy is described as the energy needed to remove the second electron from its valence shell. WebFeb 16, 2024 · On the periodic table, first ionization energy generally increases as you move left to right across a period. This is due to increasing nuclear charge, which results in the outermost electron being more strongly bound to the nucleus. Why does the first ionization energy decrease as you move down a group?
