Covalent Bonds and Lewis Structures

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What is a double covalent bond?

Back

A double covalent bond is formed when two pairs of electrons are shared between two atoms.

Front

How many valence electrons does hydrogen have?

Back

Hydrogen has 1 valence electron.

Front

How are covalent bonds formed?

Back

Covalent bonds are formed when atoms share electrons.

Front

What is the significance of valence electrons in covalent bonding?

Back

Valence electrons determine how atoms bond with each other and the number of bonds they can form.

Front

What is a Lewis structure?

Back

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

Front

What does a single line represent in a Lewis structure?

Back

A single line represents a single covalent bond, indicating the sharing of one pair of electrons.

Front

What does a double line represent in a Lewis structure?

Back

A double line represents a double covalent bond, indicating the sharing of two pairs of electrons.
