Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table.

These are the man-made chemical elements with atomic numbers greater than that of the heaviest natural element, uranium, which has the atomic number 92. At the present time, eleven transuranium elements have been created and identified, with a total of nearly one hundred isotopes.

Nonmetals are elements that generally cannot conduct electricity. Examples of nonmetals include hydrogen, carbon, chlorine, and helium. Properties of nonmetals include a relatively low boiling point, and poor conductivity; solid nonmetals are dull and brittle.

Examples of metals are aluminium, copper, iron, tin, gold, lead, silver, titanium, uranium, and zinc. Well-known alloys include bronze and steel. The study of metals is called metallurgy.

Few examples of metals are iron, gold, silver, aluminium, copper, etc. Physical Properties of Metals: ❖ Solid: Metals are solids at room temperature, except mercury, which is liquid at room temperature. They are generally hard and strong but sodium and potassium are soft solids and can be cut with a knife.

The essential nonmetallic elements are H , B , C , N , O , Si , P , S , Cl , Se , Br , and I (and possibly As ).

Oxygen which is 21% by volume helps in the respiration process. It is also used for manufacturing of steel and provides high temperature in metal fabrication process. Oxygen cylinders are used in hospital.
