Group 5 and 6 have a different electronic structure, with group 6 having one extra electron that group 5.

If we look at Hunds rule, which states that electrons must occupy orbitals individually bef...

pH is calculated using the equation pH=-log[H+]. The concentration of H+ ions, therefore, needs to be calculated. The amount of each substance can be calculated by multiplying the concentration by the vol...

Phenylamine is a weaker base than ethylamine because the lone pair on the nitrogen atom in phenylamine is spread into the delocalised electron ring in benzene, therefore is less available for protonation ...

The answer for this stems from the very definition of what a transition metal is: a metal that can form one or more stable ions with partially filled d-subshell. The partially fill d-subshell part is cruc...

We know from GCSE that Gaining of electrons is reduction; and Loss of electrons is oxidation. This can be remembered by the pneumonic: 'OIL RIG' :Oxidation Is Loss Reduction Is Gain.

At A-level it ...
