A prefix meaning 'two'.

Electron

A negatively charged subatomic particle.

Positive charge (in chemical context)

Indicates an atom or ion has lost electrons.

Dissociate

To break apart into ions when dissolved in a solution.

Arrhenius acid

A substance that produces hydrogen ions (H+) when dissolved in water, fully breaking apart.

Strong Arrhenius acid
