Diagram of the Bohr atomic model for a nitrogen atom, showing a central nucleus with protons and neutrons, surrounded by two rings of orbiting electrons. Labels identify protons, neutrons, electrons, and electron orbits.

The Structure of an Atom Explained

Simple diagrams of protons, neutrons, and pions display yellow quark and green antiquark spheres connected by purple ribbon-like gluons, illustrating the internal structure of these atomic particles.

Figure 13: Nuclear vibratory motion in the giant dipole resonance. Protons and neutrons move in opposite directions.

Diagram showing the sequence of uranium nucleus fission after being struck by a neutron: the nucleus absorbs the neutron, deforms, splits into fragments, releases more neutrons and gamma rays, and emits beta particles as the fragments decay. Labels identify neutrons, protons, beta particles, and gamma rays, with accompanying explanatory text.
