The easiest way to understand ionisation energy is to look at the equation for ionisation.For example, the ionisation of magnesium is shown by the following:Mg---> Mg⁺ + e^- The io...

Ionisation energy decreases down the group. This is because the atomic radii also inrease down the group, making the removal of an electron from the valence shell of an atom easier, as electrons located f...

The compound's name is butan-2-ol: four carbons in the chain means the compound has the but- prefix; the alcohol group is on the second carbon, so the compound has the -2- suffix; and the functional group...
