Which particle is negatively charged?

The electron is the particle that carries a negative charge. In the realm of atomic structure, particles can be categorized based on their charges: protons have a positive charge, neutrons are neutral (having no charge), and electrons carry a negative charge.

Electrons play a crucial role in chemical bonding and electricity. Their negative charge enables them to interact with positively charged protons in the nucleus, forming stable atoms. Additionally, the movement of electrons in conductors is what constitutes electric current.

Understanding the charge of electrons is fundamental to various concepts in biology, such as the formation of molecules, the role of ions in cellular processes, and the functioning of enzymes. This knowledge allows students to appreciate the relationship between atomic structure and biological functions at a molecular level.
