Protons are positively charged subatomic particles that are found in the nucleus of every atom. Together with neutrons, they form the nucleus of an atom, while electrons orbit around the nucleus. Protons are crucial for determining the chemical and physical properties of an element. The number of protons in an atom determines its atomic number, which in turn identifies the element. For example, all atoms with one proton are hydrogen atoms, while atoms with six protons are carbon atoms. Protons also play a key role in the stability of the nucleus, as they help balance the repulsive forces between positively charged protons. In addition to their role in atomic structure, protons are also used in medical treatments such as proton therapy, a type of radiation therapy that targets tumors with precision while minimizing damage to surrounding healthy tissue. The study of protons continues to be a vital area of research in physics and chemistry, unlocking new insights into the nature of matter.
