Covalent Bonding

Front

What is a covalent bond?

Back

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

Front

How many valence electrons does a carbon atom have?

Back

4

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 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

How many single bonds can a carbon atom form?

Back

A carbon atom can form 4 single bonds.

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

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

How many double bonds can a nitrogen atom form?

Back

A nitrogen atom can form 3 bonds, which can include single or double bonds.

Front

What is resonance in chemistry?

Back

Resonance is a concept used to describe the delocalization of electrons in molecules where the bonding cannot be expressed by a single Lewis structure.

What is the molecular geometry of methane (CH4)?

Back

The molecular geometry of methane is tetrahedral.
