The only stable, and only naturally-occurring isotope of gold has mass number of 197. This is the number of protons and neutrons in each nucleus.
Gold's atomic number is 79. This is the number of protons found in each gold atom. This determines its place in the Periodic Table, and its chemical properties: it is the defining property of gold.
A nucleus with a different number of neutrons and the same 79 protons would be a different isotope with a different mass number; a nucleus with a different number of protons would not be gold, but some other element.
The mass number of Gold is 197.
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 mass number of gold is 197. This number represents the total number of protons and neutrons in the nucleus of a gold atom.
The mass number is the sum of protons and neutrons in the nucleus of an atom. In this case, an atom of gold with 79 protons and 118 neutrons would have a mass number of 197 (79 protons + 118 neutrons = 197 mass number).
The number of atoms in a bar of gold depends on the mass of the bar. To calculate the number of atoms, you would need to know the mass of the bar and the atomic mass of gold. You can use Avogadro's number to convert from grams to atoms.

Gold is a metal element. Atomic mass of it is 197.
The mass number for Gold(Au) is 196.967
The mass number is the sum of protons and neutrons in the nucleus of an atom. In this case, an atom of gold with 79 protons and 118 neutrons would have a mass number of 197 (79 protons + 118 neutrons = 197 mass number).
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.
The number of atoms in a bar of gold depends on the mass of the bar. To calculate the number of atoms, you would need to know the mass of the bar and the atomic mass of gold. You can use Avogadro's number to convert from grams to atoms.
Gold is a metal element. Atomic mass of it is 197.
To find the number of moles of gold, first calculate the molar mass of gold, which is 197 g/mol. Then, divide the given mass of gold by the molar mass to find the number of moles. In this case, 3.60x10-5g ÷ 197 g/mol ≈ 1.83x10-7 moles of gold.
Gold is a metal element. Atomic mass of it is 197.
mass number is simply the addition of the proton number and neutron number. we also know that proton number of the element is similar to atomic number. we also know that 79 + (197-79) is the no. of neutron no. of the gold. hence when atomic no. of the gold is 79 its atomic mass or mass number is 197.
