The atom with the highest group number is usually the central atom.

Lone pairs of electrons do not need to be included in the structure.

A Lewis structure includes all the valence electrons in the species.

A single bond contains two electrons and is represented by a solid line.

The placement of atoms of elements can change.

Equivalent structures can be used to represent the ion.

The number of atoms of elements can change.
