What is a Lewis structure?

Back

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

Front

What is a lone pair?

Back

A lone pair is a pair of valence electrons that are not shared with another atom and are not involved in bonding.

Front

What is a bond angle?

Back

A bond angle is the angle formed between three atoms across at least two bonds.

Front

What is hybridization in chemistry?

Back

Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals suitable for the pairing of electrons to form chemical bonds.

What is the hybridization of carbon in methane (CH4)?

Back

The hybridization of carbon in methane is sp3.

Front

What type of bond is formed between two nonmetals?

Back

A covalent bond is formed between two nonmetals.

Front

What is a sigma bond?

Back

A sigma bond is the strongest type of covalent bond formed by the head-on overlap of atomic orbitals.

Front

What is a pi bond?

Back

A pi bond is a type of covalent bond that is formed by the side-to-side overlap of p orbitals.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is metallic bonding?

Back

Metallic bonding is the type of chemical bonding that occurs in metals, characterized by a sea of delocalized electrons that are free to move around.
