It is a gold isotope.
isotope
Assuming there is a blank between "a" and "of," 178Au is an unstable isotope of gold. The 79 is its atomic number (number of protons), and 178 is the atomic mass (number of protons + numbers of neutrons).
The atomic symbol for gold is Au and its atomic number is 79.
_The 79th element on the periodic table is Gold, Au
Au is the chemical symbol for gold. It has an atomic number of 79 meaning it has 79 protons and 79 electrons. I assume that is what you mean
79 protons 118 neutrons 76 electrons
79
#79 is Gold (Au).
Au, gold, is atom number 79, so in its (neutral) elemental form it has 79 electrons.
For gold (Au), atomic number = 79, so it has 79 protons and 79 electrons. The number of neutrons can vary depending on the isotope of gold, but a common isotope, Au-197, has 118 neutrons.
