Chemistry - Lewis Dot Structures

A Lewis Dot Structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

Nitrogen has 5 valence electrons.

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

A lone pair is a pair of valence electrons that are not shared with another atom and are not involved in bonding.

NH3 has 1 lone pair.

A triple bond is formed between Carbon and Nitrogen in HCN.

CO2 has a total of 16 valence electrons.

Hydrogen (H) and Lithium (Li) are exceptions to the octet rule and can have fewer than 8 valence electrons.

There are 0 lone pairs on the Carbon atom in CO2.

A double bond is a type of chemical bond where two pairs of electrons are shared between two atoms.
