The periodic table consists of 72 naturally occurring metals: six alkali metals, six alkali earth metals, 30 transition metals, seven other metals, seven metalloids, and 16 rare earth elements. Of these, four are liquids or melt close to room temperature.
The only common metals that occur as pure native elements are gold, silver, copper, lead, platinum, palladium, iridium, osmium, iron, and mercury. Native tantalum, tin, and zinc exist but are extremely rare.
Native arsenic, antimony, bismuth, selenium, and tellurium exist and are very rare and are not strictly speaking metals (they are classed as semi-metals).
All the other metals on the periodic table exist only in combination with other elements.
