What is a covalent bond?

Back

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

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 significance of the periodic table's groups?

Back

Elements in the same group have similar chemical properties and the same number of valence electrons.

Front

What is an ion?

Back

An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net charge.

Front

What is the difference between an ionic bond and a covalent bond?

Back

An ionic bond is formed by the transfer of electrons, while a covalent bond is formed by the sharing of electrons.
