An atom is the basic unit of matter that makes up all elements. An atom is made up of three types of particles: protons, neutrons, and electrons.
Protons are positively charged particles that are found in the nucleus, or center, of an atom. Neutrons are neutral particles that also reside in the nucleus. Electrons are negatively charged particles that orbit the nucleus in shells.
The number of protons in an atom’s nucleus determines what element the atom is. For example, an atom with one proton is hydrogen, while an atom with two protons is helium. The number of neutrons in an atom’s nucleus can vary, and atoms with the same number of protons but different numbers of neutrons are known as isotopes of that element.
Atoms can combine with each other to form molecules and other compounds. The properties of the resulting compound are determined by the types of atoms involved and the way they are bonded together.
Overall, atoms play a crucial role in the study of matter and its behavior, and their understanding is critical for many areas of science and technology, such as chemistry, biology, School Analytics and engineering.
