Al has the higher first ionisation energy. Mg electronic configuration is [Ne]3s2 whereas Al configuration is [Ne]3s23p1. To remove the electron from Al, it has to be remo...
Ionisation energy is the energy required to remove one electron from an isolated gaseous atom (in its ground state). This generates a cation (ion with a positive charge).Both Mg and Al are in period...

Molecular shape is based on VSEPR Theory which states that electrons in lone pairs repel other electrons in lone pairs the most. Electrons in lone pairs repel electrons in bonding pairs less and electrons...
In A Level Chemistry, the word aromatic means a molecule’s structure contains at least one cyclic ring which has a delocalised pi electron cloud above and below it. This occurs from unbonded P orbital ele...
