Define a covalent bond.

Back

A chemical bond formed by the sharing of electron pairs between atoms.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What are valence electrons?

Back

Electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is electronegativity?

Back

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

Front

What is a nonpolar covalent bond?

Back

A bond formed between two atoms with an electronegativity difference of 0.
