loads - look at the 72 elements before it in the periodic table
Hafnium is a single element and therefore nonpolar.
The element with 72 electrons is Hafnium (Hf). Hafnium has an atomic weight of 72 and is a period 6, group 4 transition metal. It is the first element after the Lanthanides. Hafnium has 72 electrons in 6 shells with 2 electrons in the outer shell.
Hafnium is not a dangerous metal; also is a very rare element.
Hafnium is a natural chemical element; hafnium hasn't minerals but it is associated with zirconium (unrefined zirconium contain approx. 2 % hafnium).
It is a metallic element

Hafnium is an element not a rock. Hafnium is never found in nature pure form so does not fit into any groups. Hafnium is a chemical element, a metal placed in the group 4 and period 6 of the periodic table of Mendeleev.
A compound is not lighter than an element, if that element is part of the compound. Some compounds, like H2O would be lighter than, say, the element lead, but it is not lighter than the elements that make it up, i.e. hydgrogen and/or oxygen.
No, it is not. Hafnium is a transition metal. Use the link below for more information.
