Some facts about elements

1.	Some facts about elements
Answer» Facts about elements: 1. Calcium isn't found free in nature, but it can be purified into a soft silvery-white alkaline earth metal. 2. Carbon has the highest melting/sublimation point of the elements. The melting point of diamond is 3550°C, with the sublimation point of carbon around 3800°C. Helium is colorless, odorless, tasteless, non-toxic, and inert. 3. Hydrogen is the most abundant element. About 75% of the element mass of the universe is hydrogen. 4. The single largest use of iron is to make steel, an alloy of iron and a smaller amount of carbon. According to achaeological records from Anatolia, man has been producing steel for at least 4,000 years. 5. Lithium metal is made by electrolysis of fused lithium chloride.
