hat is carbon dating? - ANSWER The process of using the radioactive isotopes in carbon-14. All living things contain carbon-14. Carbon-14 decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food. Once the organism dies, however, it cannot absorb carbon-14. This means that the amount of the radiocarbon in its tissues steadily decreases.

Physical Science Praxis 5442 Exam Study Guide. Atomic Structure - answerAn atom is a complex arrangement of negatively charged electrons arranged in defined shells about a positively charged nucleus. This nucleus contains most of the atom's mass and is composed of protons and neutrons (except for common hydrogen which has only one proton). All atoms are roughly the same size Protons - answerPositively charged particles found within atomic nuclei Neutrons - answerA subatomic particle of a...
