Chemistry - Lewis Dot Structures

Front

What is a Lewis Dot Structure?

Back

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.

How many valence electrons does Nitrogen (N) have?

Back

Nitrogen has 5 valence electrons.

Front

What is the octet rule?

Back

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.

Front

What is a lone pair?

Back

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

Front

How many lone pairs does NH3 (Ammonia) have?

Back

NH3 has 1 lone pair.

Front

What type of bond is formed between Carbon (C) and Nitrogen (N) in HCN?

Back

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

Front

How many total valence electrons are in CO2 (Carbon Dioxide)?

Back

CO2 has a total of 16 valence electrons.

Front

Which elements are exceptions to the octet rule?

Back

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

Front

How many lone pairs are on the Carbon atom in CO2?

Back

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

Front

What is a double bond?

Back

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