How many pure metals are there?
Around 95 of the 118 elements in the periodic table are metals (or are likely to be such). The number is inexact as the boundaries between metals, nonmetals, and metalloids fluctuate slightly due to a lack of universally accepted definitions of the categories involved.

Is lead a pure metal?
Lead is found in nature, rarely in pure form but in ores with other metals — the most abundant one in the Earth’s crust being galena (PbS). Natural formation of lead occurs by radioactive decay of uranium and thorium through radon (222Rn).
Why is lead more common than gold?
