Electrons are known to carry which type of charge?

Electrons are fundamental subatomic particles known for carrying a negative charge. This characteristic is essential in the field of electromagnetism and helps define how electrons interact with other charged particles. The negative charge of electrons plays a key role in the structure of atoms, as they orbit the positively charged nucleus, which consists of protons and neutrons. This balance of charges is crucial for the stability of matter and contributes to chemical bonding and electrical conductivity.

Understanding the nature of electronic charge is fundamental in various applications, including electronics, electrology, and physics. The other options—positive, neutral, and variable—do not accurately describe the charge of an electron. Protons carry a positive charge, neutrons are neutral and do not possess any charge, and the concept of a variable charge does not apply to electrons in this context. This makes the identification of electrons as carrying a negative charge not only correct, but an essential principle in understanding electricity and atomic structure.
