Atoms 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 positively charged protons and neutral neutrons. Different numbers of these particles create various elements, each with a unique atomic number. Hydrogen, the simplest element, has one proton. Protons repel each other but are held together by a strong nuclear force, allowing atoms to exist. Atoms combine to form molecules.
