Atomic Structure Atoms: protons, neutrons, and electrons. The number of protons determines the identity of the element. Some atoms of the same element have a different number of neutrons. These are called isotopes. Example: 12 C, 13 C, and 14 C =>

Electronic Structure Electrons: outside the nucleus, in orbitals. Electrons have wave properties. Electron density is the probability of finding the electron in a particular part of an orbital. Orbitals are grouped into “shells,” at different distances from the nucleus. =>
