Its relative density is 1,74 and it’s density 1740 kg/m 3 (0.063 lb/in 3 or 108.6 lb/ft 3). Reaction of Metals with Oxygen Almost all metals react with oxygen to form metal oxides. Chemical properties of matter describes its "potential" to undergo some chemical change or reaction by virtue of its composition. Chemical element, metallic, symbol Mg, situated in group IIa in the periodic table, atomic number: 12, atomic weight: 24,312. Pure iron is fairly soft and can easily be shaped and formed when hot. Its surface is usually discolored by corrosion, since it combines readily with the oxygen of the air in the presence of moisture. Chemistry is a physical science related to studies of various atoms, molecules, crystals and … Chemical Properties and Changes. Iron is easily magnetized. Cast iron is one of the oldest ferrous metals commonly used in outdoor ornaments and construction. Iron is a shiny, bright white metal that is soft, malleable, ductile and strong. Examples of chemical properties include reactivity, flammability and oxidation states. So, the metallic properties of elements tends to decrease across a period and increase down a … When two elements are joined in a chemical bond, the element that attracts the shared electrons more strongly has more electronegativity. Remember, the definition of a chemical property is that measuring that property must lead to a change in the substance’s chemical structure. Below are some example elements and compounds and their chemical properties. Most steel produced today is plain carbon steel or simply carbon steel. For e.g. It contains 2 percent to 5 percent carbon content. A chemical property is a characteristic that can only be seen when the material changes and a new material is formed.
