Define an atom, and describe how and what subatomic particles compose it. Use your best grammar to write 3–5 sentences on this topic.

Thank you in advance to whom it may concern!

Answer:

Step-by-step explanation:

Elementary particles, commonly known as subatomic particles. Any of the several discrete, self-contained forms of matter or energy that constitute the fundamental constituents of all matter. Despite being negatively charged and nearly massless particles, subatomic particles have electrons that are typically atom-sized. Additionally, it comprises positively charged protons and electrically neutral neutrons, the heavier constituents of a small but extremely compact nucleus. The only known subatomic particles, however, are by no means these fundamental atomic building components. For instance, quarks are the subatomic particles that make up protons and neutrons, while electrons are merely one of a class of subatomic particles that also includes muons and neutrinos. By interacting with cosmic rays in the Earth's atmosphere, scientists have discovered and described more uncommon subatomic particles, such as positrons, the antimatter of electrons. The field of elementary particles has expanded dramatically with the construction of powerful particle accelerators to study the high-energy collisions of matter with electrons, protons and other particles. When high-energy particles collide, the collision energy becomes available for the creation of subatomic particles such as mesons and hyperons. Ultimately, the revolution that began in the early 20th century with the theory of matter-energy equivalence, completed by the discovery of the effect of force on the exchange of 'force' particles such as photons and gluons, transformed the study of elementary particles. did. I was. Over 200 subatomic particles have been discovered as a result of the reaction or collision of cosmic rays produced in particle accelerator experiments. Most of them are highly unstable and live for less than a millionth of a second. Theoretical and experimental studies of particle physics, the study of elementary particles and their properties, have allowed scientists to understand more clearly the nature of matter and energy, and the origin of the universe. The Standard Model is a theoretical foundation that takes into account particle physics as it is now understood. For all identified subatomic particles, the Standard Model provides a classification scheme based on theoretical descriptions of the basic forces of matter.

Answer:

An atom is a particle of Matter that defines a chemical element. While they compose of three different subatomic particles protons, neutrons, and electrons. The protons and neutrons are located in the nucleus while the electrons are located around the atom.
