General Principle of Liquefaction The liquefaction of a gas requires high pressure and low temperature. The pressure brings the molecule of a gas close to each other. Low temperature causes to increases attractive forces. For every gas there is a temperature above which the gas […]
“The mass of one atom of an element compared with the mass of one atom of carbon taken as 12 is called relative atomic mass of the element.” Explanation: The mass of one atom of magnesium is two times the mass of one atom of […]
“When a molecule loss or gain one or more electrons, is called Molecular Ion or Polyatomic ion.” Examples of Polyatomic ions: CH4+, CO+, N2+ etc. Formation of Molecular Ion: Cationic molecular ions are more abundant than anionic Molecular ions. These ions can be […]
“A particle carrying either negative or positive charge, is called Ion.” Types of Ions: There are following two types of ions depending upon their nature of charge. Cation Definition: The ion which has positive charge is called Cation. e.g., Na+1, Ba+2, Al+3 etc. […]
Here in this topic we will discuss definition of molecule in chemistry, molecule examples and properties of molecules. “Smallest particle of elements or compounds which may survive solely is called Molecule.” Composition & Molecule example: It consist of, One atom of the element […]
Following are the main Branches of Chemistry. Organic Chemistry: “The branch of chemistry which deals with the compounds which have carbon as basic constituent elements attached with each other through catenation, is called organic Chemistry.” In other words, Organic chemistry is also called “carbon chemistry.” It is […]
