Web16 okt. 2024 · Ionisation energies are measured in kJ mol-1 (kilojoules per mole). They vary in size from 381 (which you would consider very low) up to 2370 (which is very … Web3. Ionization Energy. IE increases IE increases. Ionization energy (IE) is the energy required to remove the highest-energy electron from a neutral atom. In general, ionization energy increases across a period and decreases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant.

Web8 apr. 2024 · As we move down group 17, the ionization energy decreases. This is because as we move down the group the size of the atom increases which decreases the attraction of the valence electrons and the valence electrons therefore only little ionization energy is required to remove an electron from the valence shell from any halogens. WebThe ionisation energy down a group decreases due to the following factors: The number of protons in the atom is increased, so the nuclear charge increases But, the atomic …
