Conservation genetics uses a combination of ecology, molecular biology, population genetics, mathematical modeling, and evolutionary taxonomy (the study of family relationships). It is both a basic and an applied science. First, scientists must understand the genetic relationships among the organisms they're studying.

Quick Answer. The chemical properties of an element are determined by the electrons in the partly filled outermost shell. This shell is referred to as the valence shell. There are one or more subshells in each shell, and each subshell is made up of one or more atomic orbitals.
