II. The Chemistry Of Life (Chapter 2: Background for Biochemistry)
A. Key Forces Acting on Matter
B. Matter1. atoms: a basic unit of matter with a specific number of protons for each electron. Atoms have a neutral charge when isolated. This means that the number of protons will equal the number of electrons in an atom.
2. elements: consists of all the same type of atoms. 3. compounds: 2 or more elements chemically bonded. 4. molecules: 2 or more atoms chemically bonded. 5. ions: an atom that is charged due to a different number of electrons and protons. 6. radioactivity: energy released when atomic nuclei are unstable due to a low number of electrons. 7. isotopes: atoms with the same number of electrons but a different number of neutrons. 8. ions: an atom that is charged due to a different number of protons and electrons. E. Chemical Bonds

C. The AtomThe Quantum Mechanical Model of the atom is the current theory of the atom that states that strong forces combine protons and neutrons the form the nucleus and have electrons surround it.
D. Sub-Atomic Particles
F. Water and It's Importance to Life
