Learning Objectives After this lecture, you should be able to: Describe and illustrate the difference between the different types of chemical bonds. Describe and draw the general structure of an atom, understanding the basic differences between electrons, protons and neutrons. Explain how/why electrons from one atom can influence those from neighboring atoms (and what the result might be). Understand the difference between polar vs. non-polar bonds and/or molecules. Describe an isotope. Given a picture of the periodic table, describe and/or illustrate the arrangement of electrons in any biologically relevant atom.

Atoms are the constituents of both living organisms and non-living matter Atoms Nucleus contains one or more positively charged proton and may contain one or more neutral neutrons Positively charged nucleus is surrounded by one or more negatively charged electrons Atoms are electrically neutral; the number of protons equals the number of electrons Electrons determine how atoms will react in chemical reactions Helium atom Elements are pure substances containing only one type of atom
