What is the charge of an electron?

The charge of an electron is negative one, which is represented as -1. Electrons are subatomic particles found in atoms and are fundamental components of atoms alongside protons and neutrons. The negative charge of an electron is crucial because it helps to balance the positive charge of protons in the nucleus of an atom, leading to the overall neutrality of atoms in their elemental state. This charge plays a key role in chemical bonding and interactions, influencing how atoms combine to form molecules. The other values listed do not correspond to the actual charge of an electron, making the choice of -1 the only accurate answer.
