Study the electron dot diagrams for lithium, carbon, fluorine, and neon in figure 6-1. choose the statement that correctly identifies the most stable of the elements. a. lithium is the most stable element because it has to lose only one electron to achieve a stable configuration. b. carbon is the most stable element because it can form four bonds. c. fluorine is the most stable element because it has to gain only one electron to achieve a stable configuration. d. neon is the most stable element because its highest occupied energy level is filled.

The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that insurance companies could discriminate based on genetic make-up. c) that since this has never been done before, we should probably not do it now. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.
