A dative covalent bond, or coordinate bond, is a bond where there is 1 pair of shared electrons between two atoms. The difference relative to a covalent bond is that in a dative covalent bond these electr...

Electrons are mobile or move in halogen molecules. Therefore, there can be an uneven distribution of electrons or electron density in halogen molecules (1 mark). This creates a temporary or instantaneous ...

A nucleophilic substitution reaction is when a nucleophile (an electron pair donor) replaces an atom or part of a molecule. In this scenario ammonia (NH₃) is the nucleophile as it contains a lo...

A covalent bond in an intramolecular bond which occurs when a pair of electrons is shared between two elements, usually two non-metals. The electrons shared are in the outer shell of the atom of each elem...

There are strong electrostatic forces of attraction between oppositely charged ions within sodium chlorides giant lattice. The strong electrostatic forces must be broken in order ...
