at his post you will be learn in Molecule name, what is molecule ? In science, a molecule is a group of atoms in a definite arrangement held together by chemical bonds. Chemical substances are not infinitely divisible into smaller fractions of the same substance: a molecule is generally considered the smallest particle of a pure substance that still retains its composition and chemical properties.Certain pure substances (e.g., metals, molten salts, crystals, etc.) are best understood as being composed of networks or aggregates of atoms or ions instead of molecular units.(www.wikipedia.org)

Hydrogen exists as a diatomic molecule H2. Liquid hydrogen boils at -252.7 ºC. Solid hydrogen has a melting point of -259.1 ºC. In the laboratory hydrogen gas may be prepared by the reaction of certain metals, such as aluminium or zinc with dilute hydrochloric or sulphuric acids, The most important property of hydrogen is its ability to burn in air.
UMPTN 1982 , at this year still consists of 50 number of problem, number 1 until 10 consists of ammonia, nitrogen, oxygen, and oxidation process, number 11-20 is about acid bacid reaction, hydroxide of metal, mass of c molecule, number 21 until 30 is about gas reaction, equilibrium of reaction, number 31 until 40 is about atom, isotop, salt concentration, and molar concentration, the last number from 41 is about electrolyte process, ion and oxidation process.
