Document Summary
Chm138h1 - lecture 1 - introduction to organic chemistry. All living things are made of organic chemicals. Found in 99% of more than 50 million known chemicals. Is a group 4a element: can share four valence electrons and form four covalent bonds (tetravalent) Is the building block of biological molecules. Has the unique ability to form chains and rings (e. g. benzene) - can form complex molecules from simple ones. H, p, s, o, n, and halogens are all common in organic compounds. Negatively charged electrons - focus of organic chemistry. Found in an electron cloud around the nucleus. Atomic diameter can be expressed as any of the following: 200 picometers (pm): 1 pm = 10-12 m. Atomic number (z) - number of protons in the nucleus. Mass number (a) - number of protons and neutrons in the nucleus. All atoms of a given element have the same atomic number.
