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).
molten material, magnetic stripes, and the ages of the rock.
Three: nonmetals, semimetals (or metalloids), and metals.
The three metals that do not corrode are gold, silver and platinum.
Most scientists regard metals in one of three groups Alkali, alkaline earth metals, and transition metals. The transition metals are further divided into lanthanides and actinides groups on the periodic table. One could also consider metals divided by ferrous and non-ferrous. This generally speaks of iron carrying metals and magnetic properties versus non-iron and nonmagnetic.
The three main metals in a periodic table are transition metals, alkali metals, and alakaline earth metals.

Marie Curie, Barbara McClintock, and Jane Goodall are three famous female scientist. While Marie Curie and her husband Pierre discovered the elements radium and polonium, Barbara McClintock worked on genetic transposition for which she received the Nobel prize. Jane Goodall was a primatologist who was an expert on chimpanzees.

They were British. They did not create the penicillin. It was discovered by Sir Alexander Fleming. Chan and Flory worked on the discovery.
