Au, which is also its only naturally occurring isotope, so gold is both a mononuclidic and monoisotopic element. Thirty-six radioisotopes have been synthesized, ranging in atomic mass from 169 to 205. The most stable of these is 195 Au with a half-life of 186.1 days. 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.

From the periodic table, a gold atom is represented by

#color(white)()_79^197'Au'#

79 is its charge (atomic number), which is both its proton number and electron number.

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.

Atomic

#197 - 79 = 118#

The mass of the electrons does not contribute significantly to the total mass of the atom and therefore can be ignored.

Gold (Au), chemical element, a dense lustrous yellow preciousmetal of Group 11 (Ib), Period 6, of the periodic table. Gold has several qualities that have made it exceptionally valuable throughout history. It is attractive in colour and brightness, durable to the point of virtual indestructibility, highly malleable, and usually found in nature in a comparatively pure form. The history of gold is unequaled by that of any other metal because of its perceived value from earliest times.
