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.
Compare subatomic particles by Particle type: Î¿ the atom is composed of subatomic particles (protons, neutrons, and electrons) that affect the properties of an atom. Particle mass: Î¿ protons and neutrons have about the same mass.ompare subatomic particles by Particle type: Î¿ the atom is composed of subatomic particles (protons, neutrons, and electrons) that affect the properties of an atom.

The electrons in the outermost occupied shell (or shells) determine the chemical properties of the atom; it is called the valence shell. Each shell consists of one or more subshells, and each subshell consists of one or more atomic orbitals.
