In terms of its charge, what distinguished feature does an electron exhibit?

Electrons are elementary particles that hold a fundamental characteristic of having a negative charge. This property is essential in understanding various concepts in physics and chemistry, particularly in the behavior of atoms and molecules. The negative charge of an electron allows it to interact with positively charged protons in the nucleus of an atom, leading to the formation of atoms and the stability of matter.

In contrast to options suggesting a positive charge, no charge, or variable charge, the clear and consistent identification of electrons as negatively charged entities is crucial for various applications, including electrical conductivity, chemical bonding, and atomic structure. Understanding the negative charge of electrons is foundational for further studies in radiation safety and the behavior of particles in different environments.
