Covalent Bonds

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 pairs of shared electrons are there in a stable molecule of oxygen (O2)?

Back

2 pairs of shared electrons.

Front

What analogy can describe a covalent bond?

Back

Lisa gives Matthew a marker so they each have 8 markers a piece.

Front

In a nitrogen molecule (N2), how many electrons do the nitrogen atoms share?

Back

6 electrons.

Front

What do we call identical elements that bond with each other, such as oxygen with oxygen?

Back

Diatomic molecule.

Front

How do covalent bonds form?

Back

By sharing valence electrons between atoms.

Front

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

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 molecule?

Back

A molecule is a group of two or more atoms bonded together, which can be of the same or different elements.

Front

What are valence electrons?

Back

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

Front

What is the octet rule in relation to covalent bonding?

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.
