Metals are generally lustrous, are able to conduct heat and electricity, have high melting points, are malleable, remain solid at room temperature and appear opaque in thin cross-sections. Non-metals have a dull appearance, are brittle, cannot conduct heat and electricity well, are transparent in th

An element's metallic properties refer to its propensity to behave like the elements that are classified as metals in the periodic table. This depends on the set of chemical properties commonly associated with the metallic elements, specifically the ability of an element to lose its outer valence el

The exact reason why the American professional baseball championship is referred to as the World Series is unclear. The term "World's Championship Series" was first used in 1903 to describe the end-of-season nine-game series between the Pittsburgh Pirates and the Boston Red Sox, then known as the Bo
