Exploring the World of Atoms Through Song

Atoms are the fundamental units of matter, forming everything in the universe. They consist of electrons, protons, and neutrons. Electrons are negatively charged and orbit the nucleus, which is made of protons and neutrons. The number of protons defines an element's atomic number. Hydrogen, the simplest atom, has one proton and one electron. Protons repel each other but are held together by a strong nuclear force, allowing atoms to exist. Different atoms combine to form molecules.
