It is known to exist in four distinct crystalline forms. This paper contains an account, as promised, of a study of the physical and chemical properties of iron carbonyl, similar to that already communicated to the Society on the properties of the analogous compound of nickel,* to which this forms the sequel. The change of one type of matter into another type (or the inability to change) is a chemical property. Its atomic mass is 55.847. Reactions to substances may be brought about by changes brought about by burning, rusting, heating, exploding, tarnishing etc. It belongs to group 8, periodic number 4 of the periodic table. Chemical properties are only observable during a chemical reaction. The main mining areas for iron are China, Australia, Brazil, Russia, and Ukraine. The melting point of pure iron is 1,536°C (2,797°F) and its boiling point is about 3,000°C (5,400°F). One of the chemical properties of iron is that it easily gets oxidized in open air, and this is why many compounds of iron (II) get oxidized into iron (III). A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. For some accounts and explanations, reference will be made to other articles where they appear, and will not be duplicated here. A physical change is a change in the state or properties of matter without any accompanying change in its chemical composition (the identities of the substances contained in the matter).
