titanium: ninth most abundant element in Earth's crust, silver grey metal.
vanadium: comparatively rare element found in clay, coal, and a few minerals.
cobalt: resembles nickel and is magnetic.
iron: most important and common metal.
copper: main ingredient in most alloys and known for it's high conductivity.
silver: excellent conductor of electricity but mostly used for jewelry.
Tungsten: very hard transition metal also melts at high temperature used to make high speed cutting tools.
metalloids:elements that have some properties of both metals and non metals.
silicon: second most abundant element on Earth. Lustrous and brittle with a valence of 4.
antimony: metalloid found free in nature and used to make storage batteries.
