What is a bond in chemistry?

Back

A bond in chemistry is a lasting attraction between atoms, ions, or molecules that enables the formation of chemical compounds.

Front

What are the main types of chemical bonds?

Back

The main types of chemical bonds are ionic bonds, covalent bonds (polar and nonpolar), and metallic bonds.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

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 the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds occur when electrons are shared unequally between atoms, while nonpolar covalent bonds occur when electrons are shared equally.

Front

What is electronegativity?

Back

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

Front

Which element is the most electronegative?

Back

Fluorine is the most electronegative element in the periodic table.

Front

What is the electronegativity difference for a polar covalent bond?

Back

The electronegativity difference for a polar covalent bond is between 0.5 and 1.9.

Front

How are electrons shared in a nonpolar covalent bond?

Back

In a nonpolar covalent bond, electrons are shared evenly between the two atoms.

Front

What is a diatomic molecule?

Back

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