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

What type of electrons are involved in the formation of a covalent bond?

Back

Valence electrons are involved in the formation of a covalent bond.

Front

How many valence electrons does oxygen have in its Lewis structure?

Back

Oxygen has two pairs and two single valence electrons in its Lewis structure.

Front

What type of bond forms between atoms with different electronegativities?

Back

A polar covalent bond forms between atoms with different electronegativities.

Front

How many valence electrons does aluminum have in its Lewis structure?

Back

Aluminum has three single valence electrons in its Lewis structure.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons.

Front

What is a Lewis structure?

Back

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

Front

What is a non-polar covalent bond?

Back

A non-polar covalent bond is a type of bond where electrons are shared equally between two atoms.

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.
