Radioactive Dating
Radioactive dating is a process whereby a person can calculate the age of an object by measuring its rate of radioactive decay. What is Radioactive Dating? Carbon Dating Geological Dating Isotopes used in Geological Dating Radioactive Dating with Uranium-238 What is Radioactive Dating? Radioactive dating is a process whereby a person can calculate the age of an object by measuring its rate of radioactive decay. This is because the rate of decay is consistent with any particular isotope and is not affected by outside environmental influences. A sample of radioactive material will contain a certain amount of the unstable isotope that has not yet decayed into its stable form. By comparing the amount of unstable and stable isotopes we can calculate the age of some materials. In a particular sample of radioactive material it takes a set amount of time for half of the nuclei to succumb to radioactive decay which is called the radioactive half-life. Carbon Dating All life forms intake carbon during their lives and a small proportion of that carbon is in the form of carbon-14 (due to cosmic rays). Within the body of living organism the percentage of carbon-14 and carbon-12 meet a certain level which is sustained until its death. At this point no more carbon is ingested and the ‘clock’ starts. The levels of carbon-14 (6C14) start to drop as it decays into a nitrogen ion (7N14) and by knowing the rate of decay you can compare the levels carbon-12 and carbon-14 to calculate the approximate age of the organic material. This method however is only suitable...
Isotopes – what are they?
Isotopes are the variations of elements. An element is defined by the amount of its protons while an isotope of that element has different amount of neutrons. What are isotopes? How are isotopes formed? Stable Isotopes Unstable Isotopes (Radioactive Isotopes) Alpha Radiation or Alpha Decay Beta Radiation or Beta Decay Radioactive half-life What are Isotopes? Here is the chemical symbol for helium as you might see it on a periodic table. The number at the top is known as the atomic number and is actually the number of protons that are found in the atom. The number at the bottom is the atomic mass of the element. As electrons are considered to little or no mass the atomic weight is the amount of protons and neutrons normally found in that element. While the atomic number of an element will always remain the same (hydrogen will always have one proton, helium will always have two etc) the atomic mass can change naturally. This happens when more neutrons are added to the element in some way. How are isotopes formed? Taking the most basic element, hydrogen, it has a one proton and one electron as shown in the diagram. In the process of nuclear fusion in the sun these hydrogen atoms are split into individual elements of protons and electrons that float around in the form of plasma. The pressure and heat that cause the hydrogen to turn to plasma, rather than gas, also make it easy for the particles to form new atoms. When one of these free protons collides with a hydrogen atom...

Oxygen
Oxygen is the third most abundant element in the universe and highly reactive forming compounds with almost all the other elements Basic Information Discovery Sources The Ozone Layer Uses of Oxygen Living Organisms Oxygen rich combustion Fuel Cells Cell Structure Absorption Lines Emission Lines Oxygen Basic Information Classification: non-metal Atomic Mass: 15.99 u Density: 1.429 g/l Colour: None Boiling Point: 90.188 K (-182.962°C) Melting Point: 54.36 K (-218.79°C) Discovery Oxygen was discovered in 1774 by English chemist Joseph Priestly, which he isolated by heating mercuric oxide (HgO). Sources Oxygen is the third most abundant element in the universe and highly reactive forming compounds with almost all the other elements. At the creation of earth it combined with silicon to create our crust, hydrogen to create water and it makes up 20.8 % of the air in atmosphere. The Ozone Layer Ozone is an allotrope (an allotrope is another form of an element for example graphite and diamond are allotropes of carbon) of oxygen with the chemical symbol O3. In our upper atmosphere the ozone layer protects the inhabitants of earth from harmful U.V. rays released by the sun. Ozone layer is also found much closer to the earth’s surface where its effects can cause respiratory problems for people especially those who suffer from asthma etc. Uses Living Organisms Oxygen is necessary for all life. It is used by every cell in living organisms, except somatic cells (sperm and egg cells), to produce the energy they require through aerobic...
