Covalent Bonding Mastery Test

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 electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

What is the electronegativity difference that indicates the formation of a nonpolar covalent bond?

Back

Less than 0.5.

Front

What do the lines in covalent structures represent?

Back

Bonded electrons.

Front

What is the main characteristic of a covalent bond?

Back

The sharing of electrons.

Front

What type of elements typically form covalent bonds?

Back

Nonmetals.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between two atoms.

Front

What is the electronegativity difference that indicates a polar covalent bond?

Back

Between 0.5 and 2.0.

Front

What is an ionic bond?

Back

An ionic bond is a chemical bond formed through the transfer of electrons from one atom to another.

Front

What is the typical formation of an ionic compound?

Back

An ionic compound is formed from a metal and a nonmetal.
