Elements are composed of a specific type of atom from "summary" of Chemistry by Russell Kuhtz
Each element is composed of a unique type of atom. Atoms are the fundamental building blocks of matter and are the smallest unit of an element that retains its unique properties. The number of protons in the nucleus of an atom determines its identity as a specific element. For example, all atoms of oxygen have 8 protons in their nucleus, distinguishing them from atoms of other elements. Atoms are composed of subatomic particles, including protons, neutrons, and electrons. Protons have a positive charge, neutrons are neutral, and electrons have a negative charge. The number of protons in an atom determines its atomic number, which is unique to each element. The total number of protons and neutrons in an atom's nucleus is known as its atomic mass. The arrangement of electrons in an atom's electron cloud determines its chemical properties. Electrons are located in s...
