The study of bones is called Osteology A new born has about 300 bones in its body, many of which fuse later in life to form 206 bones in an adult. Bones are chiefly made up of Calcium Phosphate and Collagen (a protein). The longest bone in the human body is the Femur or the thigh bone The smallest bone is located in the ear and known as the stapes Bones are attached to bones by tough, fibrous tissues known as ligaments The flexible tissue in the interior of bones is known as the bone marrow. Red and white blood cells are produced in the bone marrow. Hyoid bone located at the base of the tongue is the only bone not attached to any other bone in the body. The axial skeleton consists of the bones of the skull, ear, rib cage, verbral column, sternum and the hyoid bone. (total 80 bones)
Facts about period Table
Facts about Periodic Table The Periodic Table was createa py umItry Mendeleyev, a Russian chemist and professor in 1869. The Periodic Table has seven rows or periods. The present Periodic Table has room only for 118 elements. Lanthanides is a group of 15 elements from atomic number 57 to 71. Together with Scandium and Yttrium they are known as rare earth elements. Rare earth elements which are 17 in number are actally not rare. Most of them are commonly found Actinides is a group of 15 elements from atomic number 89 to 10.3 All actinides are radioactive. The Periodic Table has 18 columns or groups. Some important groups are listed below. Group 1 - Alkali metals or Lithium group consists of Lithium, Sodium, Potassium, Rubidium, Cesium and Francium. Hydrogen is not an alkali metal even though it is listed in the first column.
Group 2 Alkaline earth metals or Beryllium group consists of Beryllium, Magnesium, Calcium, Strontium, Barium and Radium. Group 15 - Pnictogens or Nitrogen group consists of Nitrogen, Phosphorus, Arsenic, Antimony, Bismuth and Moscovium. Group 16 - Chalcogens or Oxygen group consists of Oxygen, Sulphur, Selenium, Tellurium, Polonium and Livermorium. Group 17 Halogens or Flourine group consists of Flourine, Chlorine, Bromine, lodine, Astatine and Tennessine. Group 18 - Noble gases or Helium or Neon group consists of Helium, Neon, Argon, Krypton, Xenon, Radon and Oganesson.

Welding It is process for joining similar metals by melting and fusing the base metals as well as the filler metal. Welding is usually used with ferrous-based metals such as steel and stainless steel. The temperature range of welding is 800 C - 1635 C. Welded joints are the strongest of joints Brazing It is a process in which two close-fitting parts are joined by using a fhller material which is heated above its melting point and distributed in the gap by capillary action. A chemical cleaning agent known as flux is used to prevent oxidation of metals being heated. Temperature
