caption: The image shows a diagram of the structure of a molecule, with a white background and text written on it. The diagram is a representation of the electron structure, which is composed of a nucleus, protons, electrons, and quarks. The nucleus is surrounded by electrons and protons of various sizes and shapes, and the electrons are arranged in a circular pattern around the nucleus. The text on the diagram provides further information about the structure, such as the number of protons and neutrons in each molecule.
