Understand that the atomic number of an element is the number of protons in the nucleus of an atom of that element, and it uniquely identifies the element on the periodic table.
Recall that mercury (Hg) is a transition metal located in period 6 and group 12 of the periodic table.
Use a periodic table to locate mercury (Hg) and find the number associated with it, which is its atomic number.
