About it
Everything around you is made of atoms. Each one has a tiny heavy center, the nucleus, made of protons and (in almost every atom) neutrons, with electrons around it. The number of protons decides which element it is: carbon has 6, oxygen 8 and gold 79. Pick any of the 118 elements in the Splash tab.
This model draws the electrons in rings called shells, an idea of Niels Bohr's from 1913; pick the Cloud style for a truer picture, or Every nucleon to see all its protons and neutrons. Tap it and the electrons whirl faster until each shell blurs into a glowing ring, then slow down. The nucleus is tens of thousands of times smaller than the whole atom, which is mostly empty space.
