A chemist investigating a sample of lithium found that some lithium atoms have a lower mass than other lithium atoms. The chemist drew models of the two different types of lithium atoms, as shown on the following slide.. There are about 100 different types of atoms. An element is a substance which contains only one type of atom. Atoms. Atoms. The Periodic Table. The Periodic Table. Element, Compound, Mixture. Element, Compound, Mixture. Unit 1: ALCHEMY.

Two Methods. Which isotopes?. Binding Energy. What holds an atom together?. Forces of Nature and Atomic Structure:. Band (Island) of Stability. N/Z ratio. Number of stable isotopes. Isotope trends among the elements:. Atoms are neutral. Protons = Electrons. There are special kinds of atoms..... Ions. Isotopes. Ions. An Ion is an atom that has gained or lost ELECTRONS, so it has an overall charge. If an atom gains electrons, it’s overall charge becomes negative. If an atom loses electrons, it’s overall charge becomes positive. . Part I. . Unstable. vs. . stable. nuclei: . neutron-rich. and . proton-rich. . systems.
