Which subatomic particle has a charge of -1?

Rationale

Electron is the subatomic particle that has a charge of -1.

The electron, with its negative charge of -1, is fundamental to atomic structure and chemical bonding. It plays a crucial role in the formation of molecules and the overall behavior of atoms in various chemical reactions.

A (Proton) YOUR ANSWER

Protons carry a positive charge of +1, which is essential in balancing the negative charge of electrons within an atom. They are found in the nucleus and define the atomic number of an element. Therefore, protons do not have a charge of -1.

B (Electron) CORRECT

Electrons are the only subatomic particles with a charge of -1, making them pivotal in determining the electrical characteristics of atoms and influencing their interactions with other atoms. Their negative charge allows for the formation of bonds in chemical compounds.

C (Neutron) YOUR ANSWER

Neutrons are electrically neutral particles, meaning they have no charge at all. They reside in the atomic nucleus alongside protons and play a key role in stabilizing the nucleus but do not contribute any negative charge.

D (Quark) YOUR ANSWER

Quarks are fundamental constituents of protons and neutrons and can carry fractional charges, either +2/3 or -1/3. However, they do not exist independently in nature as single particles with a charge of -1.

Conclusion

Among the options provided, the electron is uniquely characterized by its charge of -1, distinguishing it from protons, neutrons, and quarks. Understanding the charge of electrons is essential for grasping atomic structure and the nature of chemical interactions. Without the negative charge of electrons, the behavior of matter at the atomic level would be fundamentally altered.
