Liquid sodium is being considered as engine coolant.

German Silver is an alloy of copper, nickel and zinc. It is composed of 60% copper, 20% nickel and 20% zinc. Due to its white-silverish appearance it is named as german silver but it contains no silver in it.

Coagulation is a chemical process that involves neutralization of charge. Coagulation during water treatment is designed to remove particles suspended in water.

An atom that loses or gains electrons is called as ion. Gaining of electron is negative charge and is called as Anion and lossing of eectron is called Cation.

Bond breaking is an endothermic process.

Hence, bond breakage needs an amount of energy and uses some energy based on the strength of the bond to break the bond.

Stoichiometry is a branch of chemistry deals with the calculations on reactants and products. It is based on the Law of conservation of mass where total mass of reactants is equal to total mass of products.

Law of Octaves states that "If the chemical elements are arranged according to increasing atomic weight, those with similar physical and chemical properties occur after each interval of seven elements." That is every 8th element have the same physical and chemical properties. This was established by the British scientist John Newlands in the year 1865.
