The chemical symbol for Rhodium is Rh. Period When it reacts with water it forms the spontaneously flammable gas, diphosphine which triggers the lighting of the flare. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Its properties are thus intermediate between those of chlorine and iodine. Francium is the second-least electronegative element, behind only caesium, and is the second rarest naturally occurring element (after astatine).

Because of its high chemical reactivity, barium is never found in nature as a free element. Boiling point of Phosphorus is 280°C. They used wood ash in their process and wartime shortages of wood forced them instead to burn seaweed. Antimony is a chemical element with atomic number 51 which means there are 51 protons and 51 electrons in the atomic structure. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atom—the Na+ cation. This is because they can lead to high phosphate levels in natural water supplies causing unwanted algae to grow.

Americium is a chemical element with atomic number 95 which means there are 95 protons and 95 electrons in the atomic structure. Elements are organised into blocks by the orbital type in which the outer electrons are found. 1650 - 1720. Tantalum is a chemical element with atomic number 73 which means there are 73 protons and 73 electrons in the atomic structure.
