The outer electron on aluminium is removed from the 3p sub-level, whereas the outer electron on magnesium is removed from the 3s sub-level.The 3p sub-level is higher in energy than the 3s sub-level.Alumin...
Calcium ions (Ca2+) have the same charge as magnesium ions (Mg2+) but Ca2+ ions have a larger ionic radius (as ionic radius increases down the group). This means Ca2+...
Step 1: Nitration of benzene Benzene + conc. H2SO4 + conc. HNO3 with heat & under reflux --> Nitrobenzene Step 2: Reduction of nitrobenzene Nitrobenzene + tin + con...
As you descend the group, the nuclear charge increases with the addition of further protons. Despite this, the atomic radius from the nucleus to the valence electron increases with more electron shells as...
Crude oil is a mixture of different hydrocarbons, of varying length. As they have different boiling points they can be separated.Crude oil is heated/vaporised from oil to gas.These vapours enter the fract...
