Hint: The smallest unit of ordinary matter that makes up a chemical element is an atom. Atoms that are neutral or ionised make up every solid, liquid, gas, and plasma. Atoms are very tiny, measuring around 100 picometers in diameter. Due to quantum phenomena, it is impossible to correctly anticipate their behaviour using traditional physics—as if they were tennis balls.

Complete answer:
Every atom is made up of a nucleus and one or more electrons attached to it. One or more protons and a number of neutrons make up the nucleus. Only one kind of hydrogen, the most prevalent, lacks neutrons. The nucleus contains more than 99.94 percent of an atom's mass. The protons have a positive electric charge, whereas the electrons have a negative charge and the neutrons have none. The atom is electrically neutral if the number of protons and electrons is equal. When an atom contains more or fewer electrons than protons, it has a negative or positive overall charge, and these atoms are known as ions. The electromagnetic force attracts an atom's electrons to its protons in the atomic nucleus. The nuclear force attracts protons and neutrons in the nucleus to each other. The electromagnetic force that repels positively charged protons from one another is generally stronger than this force. Under some conditions, the electromagnetic force repelling the nuclear force grows greater. The nucleus breaks in this scenario, leaving behind several components. This is a type of nuclear fission. The atomic number is the number of protons in the nucleus that determines the chemical element the atom belongs to. Copper, for example, is any atom with 29 protons. The amount of neutrons in an element determines its isotope. Chemical bonds allow atoms to join with one or more other atoms to create chemical compounds such as molecules or crystals. Most of the physical changes observed in nature are due to atoms' capacity to associate and disassociate. Chemistry is the branch of science that investigates these changes.

Note:
The fundamental notion that everything is made up of small indivisible particles is very old, and it can be found in many ancient cultures such as Greece and India. The word atom comes from the Greek word atomos, which literally means "uncuttable." This ancient notion was founded on philosophical rather than scientific reasoning, and current atomic theory does not use these principles. However, philosophers who thought that matter was ultimately granular in nature have used the term "atom" throughout history.
