What is a covalent bond?

Back

A bond formed when two atoms share one or more pairs of electrons.

Front

Back

A bond formed when one atom transfers electrons to another atom, resulting in the formation of ions.

Front

What are ions?

Back

Atoms or molecules that have a net electric charge due to the loss or gain of one or more electrons.

Front

What is the difference between a positive ion and a negative ion?

Back

A positive ion (cation) loses electrons, while a negative ion (anion) gains electrons.

Front

What is electronegativity?

Back

The tendency of an atom to attract electrons in a chemical bond.
