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 atomic number defines the chemical properties of the atom, and the neutron number determines the isotope or nuclide. The terms isotope and nuclide are often used synonymously, but they refer to chemical and nuclear properties, respectively. The atomic mass number, symbol A, equals Z+N.his radioactive decay, known as beta decay, is possible since the mass of the neutron is slightly greater than the proton. The free proton is stable. Neutrons or protons bound in a nucleus can be stable or unstable, however, depending on the nuclide.
