Covalent Bonding Review

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Front

How many electrons are needed to complete the outer shell of an atom?

Back

Atoms typically need 8 electrons in their outer shell to be stable, except for hydrogen and helium, which need 2.

Front

What is the octet rule?

Back

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

Front

How many covalent bonds does oxygen need to form?

Back

Oxygen needs to form 2 covalent bonds to complete its outer shell.

Front

How many covalent bonds does chlorine need to form?

Back

Chlorine needs to form 1 covalent bond to complete its outer shell.

Front

Which element typically forms three covalent bonds?

Back

Phosphorous typically forms three covalent bonds.

Front

What is a Lewis structure?

Back

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

Front

What is the molecular geometry of CCl4?

Back

The molecular geometry of CCl4 (carbon tetrachloride) is tetrahedral.

Front

What is the difference between a single bond and a double bond?

Back

A single bond involves one pair of shared electrons, while a double bond involves two pairs of shared electrons.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between two atoms, resulting in a molecule with a slight electrical dipole moment.
