Metals are elements that are typically malleable, ductile, conductive, and shiny.
They are used widely in construction, electronics, machinery, and jewelry.

What are 20 examples of metals?

Here are 20 examples:iron, steel, aluminum, copper, gold, silver, platinum, zinc, nickel, lead, tin, titanium, chromium, cobalt, manganese, tungsten, magnesium, palladium, rhodium, and vanadium.
Metals can be ferrous (contain iron) or non-ferrous (do not contain iron).
