U6L1 - Post Flashcard - The Covalent Bond

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond that results from the sharing of valence electrons between two atoms.

Front

What is formed when two or more atoms bond covalently?

Back

A molecule is formed when two or more atoms bond covalently.

Front

How many single covalent bonds does nitrogen form in ammonia (NH3)?

Back

Nitrogen forms three single covalent bonds in ammonia (NH3).

Front

How many pairs of unshared electrons does nitrogen have in ammonia (NH3)?

Back

Nitrogen has one pair of unshared electrons in ammonia (NH3).

Front

What type of bond is present in a hydrogen molecule (H2)?

Back

A hydrogen molecule (H2) contains a single covalent bond that results from the sharing of one pair of electrons.

Front

What are multiple covalent bonds?

Back

Multiple covalent bonds are formed when atoms share more than one pair of electrons.

Front

What are examples of multiple covalent bonds?

Back

Double covalent bonds and triple covalent bonds are examples of multiple covalent bonds.

Front

What is a double covalent bond?

Back

A double covalent bond is formed when two atoms share two pairs of electrons.

Front

What is a triple covalent bond?

Back

A triple covalent bond is formed when two atoms share three pairs of electrons.

Front

What is the significance of valence electrons in covalent bonding?

Back

Valence electrons are the electrons in the outermost shell of an atom and are involved in forming covalent bonds.
