Uses of radioisotopes carbon dating
In electrolysis, an electric current is passed through a molten (melted) compound.The electrical current breaks the compound into its elements.We have already learned that ions are atoms that are either missing or have extra electrons. They are just a little different from every other atom of the same element. Electrons don't have much of a mass when compared to a neutron or proton.Let's say an atom is missing a neutron or has an extra neutron. An atom is still the same element if it is missing an electron. For example, there are a lot of carbon (C) atoms in the Universe. Atomic masses are calculated by figuring out the amounts of each type of atom and isotope there are in the Universe.These three kinds of radiation have very different properties in some respects but are all ionizing radiation–each is energetic enough to break chemical bonds, thereby possessing the ability to damage or destroy living cells.
Natural uranium consists of three isotopes: uranium-238, uranium-235, and uranium-234. The nuclei of radioactive elements are unstable, meaning they are transformed into other elements, typically by emitting particles (and sometimes by absorbing particles).Nuclear chemistry is the study of the chemical and physical properties of elements as influenced by changes in the structure of the atomic nucleus.Modern nuclear chemistry, sometimes referred to as radiochemistry, has become very interdisciplinary in its applications, ranging from the study of the formation of the elements in the universe to the design of radioactive drugs for diagnostic medicine.(See sidebar on Davy in the calcium entry in Volume 1.) There are very few uses for potassium as a pure element.However, compounds of potassium have many important applications, the most important of which is as a fertilizer.
