¿Qué es un átomo?

The video explains that everything in the universe, including humans and devices, is made of atoms. Atoms are composed of a nucleus with protons and neutrons, and electrons orbiting around it. Protons are positively charged, neutrons have no charge, and electrons are negatively charged. The mass of an atom is concentrated in its nucleus, while its size is defined by the electron orbits. Electrons orbit the nucleus in specific shells, each with distinct energy levels. The video compares the structure of an atom to a solar system, with electrons orbiting like planets around the sun.
