Where are the mass variances in two atoms of the same elemen
Transcript of Where are the mass variances in two atoms of the same elemen
4) What comes to mind when you hear the word "radioactive" ?
5) What is the difference b/w a "stable" and "unstable" isotope ?A stable isotope does not decay and therefore, maintains a constant concentration on Earth.
Unstable isotopes can spontaneously undergo changes, transforming them into other isotopes of the same or of different elements.
6) What are some uses/applications of isotopes ? used for diagnosis, treatment, and research
Isotopes in carbon dating
Carbon dating is a method of obtaining age estimates on organic materials. dating is a variety of radioactive dating which is applicable only to matter which was once living and presumed to be in equilibrium with the atmosphere, taking in carbon dioxide from the air for photosynthesis.
Vanadium is a rare, soft, ductile gray-white element found combined in certain minerals and used mainly to produce certain alloys.
Isotopes are each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
Isotopic abundance normally refers to the fraction of a given isotope for a given element in its natural state
1) Where are the mass variances in two atoms of the same element ? The mass variances in two atoms of the same elements is in the Nucleus.
2) Why do they occur ?If the chemical element has isotopes, each isotope has a specific and different atomic mass.
3) How are two isotopes the same or different in terms of physical and chemical properties ?If the chemical element has isotopes, each isotope has a specific and different atomic mass.
how to calculate . . .
Atomic Mass =
[(mass of isotope) (%abundance) ] + [(mass of isotope) (%abundance)] /
Radon most commonly enters
homes through cracks, pores,
and openings. Radon causes lung damage which can lead to lung cancer over the course of your lifetime. Opening windows, doors, and vents. Sealing cracks and other holes in the foundation, are just some ways you can reduce Radon.
Half-life is defined as the time it takes for one-half of the atoms of a radioactive material to disintegrate. Half-lives for various radioisotopes can range from a few microseconds to billions of years
Further research . . .
Nuclear power plants harness the energy released by fission and put it to use to drive generators that produce electricity. Nuclear power plants contain reactors that create controlled chain-reaction fission, a process that continuously splits the nuclei of uranium atoms. This process produces a lot of energy, radiation, and very high heat.
