Gold is monoisotopic consisting completely of 197 Au. However there are a number of radioisotopes, some of which are listed. The gold isotope 198 Au is used for treating cancer and other conditions. In the form of a gold colloid, 198 Au has a diagnostic use for liver imaging and a therapeutic use in treatment of widespread abdominal carcinomatosis with ascites; carcinomatosis of pleura with. Gold, isotope of mass 195 Please visit the Gold element page for information specific to the chemical element of the periodic table.

What are the numbers of the subatomic particles in gold?
1 Answer
A Gold (Au) atom has 79 protons and 79 electrons. A typical gold atom has 118 neutrons, though there are 18 other radioisotopes discovered so far.
Number Of Shells In Gold
From the periodic table, a gold atom is represented by
79 is its charge (atomic number), which is both its proton number and electron number.
Mass Number In Gold
197 is its mass (atomic mass), which is the sum of its proton number and neutron number. The neutron number can be calculated by subtracting the proton mass from the total mass.
Number Of Valence Electrons In Gold
The mass of the electrons does not contribute significantly to the total mass of the atom and therefore can be ignored.
