Lead is one of the important elements found on earth. They are metallic gray in color and one of the heavy metal. It has a density of about 11.34 g/cm³. It has a high density because of its closed type of packing and face-centered cubic structure. Lead rarely occurs in its pure form on earth. It is mostly found to be present in association with its principle ore known as galena.
Thus, <u>lead is a very denser element as it has a very high density</u>.
<u>In a situation where there is a huge amount of lead in the earth's interior, the lead will be most likely to be found in the core of the earth</u>. It is because, in the present scenario, the core of the earth is comprised of denser elements namely iron (Fe) and nickel (Ni) that have an extremely high density.
