Question: 1 / 400

What is the charge of an electron?

Positive

Negative

Electrons carry a fundamental charge that is considered negative. This characteristic is pivotal in understanding electric charge interactions, as it helps define the behavior of atoms and molecules. In the context of atomic structure, the negative charge of electrons balances the positive charge of protons found in the nucleus. This balance is essential for the stability of atoms and plays a crucial role in chemical bonding and the formation of compounds.

Recognizing that electrons are intrinsically assigned a negative charge allows for a deeper understanding of phenomena such as electricity, magnetism, and quantum mechanics. The notion of charge being negative is standardized in physics and aligns with established conventions, making it a fundamental element in the study of electrostatics and electric currents.
