Structure of the Atom

- Atoms are the basic building blocks of matter.
- At the center of an atom is a nucleus, which contains protons and neutrons.
- Electrons orbit the nucleus in energy levels or shells.
- The number of protons in an atom determines its atomic number, which defines the element.
- Isotopes of an element have the same number of protons but different numbers of neutrons.
- The mass number of an atom is the sum of its protons and neutrons.

By understanding the structure of the atom, we can better understand how elements combine to form compounds like potassium bromide.
