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 have?

Back

Nitrogen has 5 valence electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have eight electrons in their valence shell, achieving a stable electron configuration.

What is the Lewis Dot Structure for ammonia (NH3)?

Back

The Lewis Dot Structure for ammonia shows nitrogen in the center with three hydrogen atoms bonded to it and one lone pair of electrons on nitrogen.

Front

What type of bond is formed when two pairs of electrons are shared?

Back

A double bond is formed when two pairs of electrons are shared between two atoms.

Front

What is the significance of lone pairs in Lewis Dot Structures?

Back

Lone pairs represent non-bonding electrons that can affect the shape and reactivity of the molecule.

Front

How do you determine the total number of valence electrons in a molecule?

Back

To determine the total number of valence electrons in a molecule, add the valence electrons of all the atoms in the molecule.

Front

What is a triple bond?

Back

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

Front

Which elements typically form covalent bonds?

Back

Nonmetals typically form covalent bonds by sharing electrons.

What is the Lewis Dot Structure for water (H2O)?

Back

The Lewis Dot Structure for water shows oxygen in the center with two hydrogen atoms bonded to it and two lone pairs of electrons on oxygen.
