What you need to know about HYDROGEN.

enthalpy is a tasteless, odourless, colourless accelerator pedal and is one of the some distinguished chemical substance chemical elements. The enthalpy pinpoint is simple and the mildest atom. atomic number 1 consists of 1 proton, which has a positive impeach up, and 1 electron, which has a negative charge as well. Hydrogen has a chemical symbol H. Its nuclear number is 1. Its atomic weight is 1.0079. The term atomic number 1 comes from 2 Greek spoken language meaning water- shiter. Hydrogen be adrift and group O hit man combine to form water. Occurrence: Hydrogen is chiefly have with atomic number 8 in form of water. Hydrogen is the most abundant element in the universe. The sun and many other stars consist mostly of enthalpy. The smashing number of hydrogen atoms in the earths crust makes it the third most abundant element on the earth, after oxygen and silicon. However, because of the small size of its atoms, hydrogen accounts for less than 1 per cent of t he crusts weight, be ninth among the elements. around of hydrogen is combined with other chemical elements, as in water. But pockets of pure hydrogen gas can attract in underground mines and cause dotty explosions. Hydrogen occurs in almost all-organic compounds. Many of the compounds found in fructify and animate being tissues are organic. Compounds called hydrocarbons contain only hydrogen and carbon. Mixtures of unhomogeneous hydrocarbons make up petroleum and natural gas.

Ammonia, most acids, many bases, and most plastics too contain hydrogen. Physical Properties: (1)It is the lightest of all the elemen ts (2)It is colourless and odourless gas (3)! Its boiling point is - 252.77 c (4)Its melting point is - 259.2 c (5)The density of hydrogen is 0,089 g/litre. Chemical Properties: (1)Hydrogen combines with oxygen to form water. (2)Hydrogen combines with nitrogen to form ammonium hydroxide (a catalyst is utilize in this reaction). (3)It reacts with sulphur to form...
