The standard SI unit is kilograms per cubic meter (kg/m3). Its atomic number is 30 and it has a large number of industrial uses. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. Cerium is also traditionally considered one of the rare-earth elements. The chemical symbol for Silicon is Si. Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily unreactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. Although classified as a rare earth element, samarium is the 40th most abundant element in the Earth’s crust and is more common than such metals as tin. It is the heaviest essential mineral nutrient. The chemical symbol for Niobium is Nb. Carbon is the 15th most abundant element in the Earth’s crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. Like the other metals of the platinum group, ruthenium is inert to most other chemicals. See also: Atomic Mass Number – Does it conserve in a nuclear reaction? It is one of the least reactive chemical elements and is solid under standard conditions. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. Its extreme rarity in the Earth’s crust, comparable to that of platinum. Rubidium is a soft, silvery-white metallic element of the alkali metal group, with an atomic mass of 85.4678. It readily forms hard, stable carbides in alloys, and for this reason most of world production of the element (about 80%) is used in steel alloys, including high-strength alloys and superalloys.
