Gold is a metal element. atomic number of it is 79.
Gold is number 79 on the periodic table
Gold (AU) is an alkaline earth metal with a relative Atomic Mass of 196.97, an atomic number of 79 in group class 1B
Golds elemental symbol is: Au
Au
Gold, with the atomic symbol AU, is element number 79.
Au. Aurum is the Latin word for gold.
The atomic symbol for gold is AU.
The mass number for Gold(Au) is 196.967
For this you need the atomic mass of Au. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.355 grams Au / (197.0 grams) = 1.80 moles Au
Hafnium is the element that has a mass number of 179. Its color is silver, its structure is hexagonal, while the number of neutrons is 106.
Gold (Au) has a mass of 196.96655 amu. Actually the mass number if gold is dependent on the number of neutrons in the mix. Gold has 79 protons and the isotope that gold is at the time will determine the mass number. So, mass number = # of protons + # of neutrons...this is for any element.

The atomic mass of Aluminum is 27.Added:The first answer is correct in itself, but on the wrong question: not concerning Au but AlAu = Gold = atom number 79, mass 197.0 a.m.u.Al = Aluminum = atom number 13, mass 26.98 a.m.u.
