Who were two or three scientists who worked on or discovered metals?
Metals in general were not discovered by scientists. No-one knows who discovered the first piece of metal. It may have been part of a meteor which fell to earth, or it may have been found in the remains of a very hot camp fire, or it may have been simply found as a nugget lying on the ground. Either way, it was almost certainly in pre-historic times. On the periodic table of elements, some metals we know today are single elements, such as aluminium, iron, tungsten, or titanium. Other metals are combinations of elements, such as steel (iron + carbon), bronze (copper + tin), etc. More than 2 or 3 scientists have worked on the periodic table of elements over the years. Some of the more exotic metallic elements (such as radium) have been discovered by individual scientists (Madam Curie in that case).
