Cobalt-60 (60C)Cobalt-60 is the most common form of radioactive cobalt that is commercially available. It is used in the form of tracer and radioactive therapeutic agent.Cobalt-60 has a half life (the time in which a radioactive element looses 50%of its radioactivity) is 5.27 years.60Co decays by beta decay to the stable isotope … [Read more...] about Cobalt-60 Facts

Groups in the Periodic Table
Alkali metals: They are members of Group I of the periodic table. They are very reactive metals and do not occur freely in nature. These metals have only one electron in their outer shell. The alkali metals include: Lithium (Li), Sodium (Na), Potassium (K), Rubidium (RB), Cesium (Cs), and Francium (Fr). Alkaline Earth metals: They are members of … [Read more...] about Groups in the Periodic Table
Atomic Number & Periodic Table
Atomic Number:It is the number of protons found in the nucleus of an atom.It is conventionally represented by the symbol Z.The atomic number uniquely identifies a chemical element. When an atom is in neutral charge, the atomic number is equals to the number of electrons.Isotope:Atoms of the same element having the same number of … [Read more...] about Atomic Number & Periodic Table
Amino Acids
Amino acids are biologically important organic compounds composed of amine (-NH2) and carboxylic acid (-COOH) functional groups, along with a side-chain specific to each amino acid.The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen, though other elements are found in the side-chains of certain amino … [Read more...] about Amino Acids
Salt and Double salts
Salt: A salt is the product of reaction between an acid and a base. It can be organic as well as inorganic. They are abundant on the earth’s crust as well as in the oceans e.g. NaCl or Sodium Chloride is deposited in large amounts on earth and ocean water. Double Salt: These are the combination of two simple salts. Unlike simple salts, Double … [Read more...] about Salt and Double salts
How Cells Divide
Cell division : Meiosis and MitosisMitosis is a process of cell duplication or reproduction during which one cell gives rise to two genetically identical daughter cells.Meiosis is a division of germ cells involving two fissions of the nucleus and giving rise to four gametes, or sex cells, each possessing half the number of chromosomes of … [Read more...] about How Cells Divide
