Chapter 1 4 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. =>

Chapter 1 5 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. =>
