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 Carbon have?

Back

Carbon has 4 valence electrons.

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons are the electrons in the outermost shell of an atom and are involved in forming bonds with other atoms.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

What is an ionic bond?

Back

An ionic bond is a chemical bond formed through the transfer of one or more electrons from one atom to another, resulting in the formation of charged ions.

Front

How many lone pairs are present in the Lewis Dot Structure of CO2?

Back

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

Front

Which element has five valence electrons?

Back

Phosphorus has five valence electrons.

Front

How many valence electrons does Nitrogen have?

Back

Nitrogen has 5 valence electrons.

Front

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

Back

The Lewis Dot Structure for NH3 shows nitrogen in the center with three hydrogen atoms bonded to it and one lone pair of electrons on nitrogen.

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.
