Covalent Bonds

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

What is the octet rule?

Back

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

Front

What type of bond is formed when two nitrogen atoms share three pairs of electrons?

Back

Triple bond.

How many covalent bonds are present in a water molecule (H2O)?

Back

2.

Front

What is the molecular formula for water?

Back

H2O.

Front

What type of elements typically form covalent bonds?

Back

Covalent bonds are typically formed between two nonmetals.

Front

What is the displayed formula for chlorine gas?

Back

Cl2.

Front

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

Back

A single bond involves one pair of shared electrons, a double bond involves two pairs, and a triple bond involves three pairs.

Front

What is a diatomic molecule?

Back

A diatomic molecule is a molecule composed of two atoms, which can be of the same or different elements.

Front

What is the significance of the shared electrons in a covalent bond?

Back

Shared electrons allow each atom to achieve a full outer shell, fulfilling the octet rule and stabilizing the molecule.
