Mole is a unit of measurement of an amount of substance.
I'll take particles to be atoms, for I assume the sample of Gold to be pure.
In that case, the number of atoms in one mole of Gold will be the Avogadro constant, or 6.022142 × 1023.
Gold has 79 protons and electrons and also 118 neutrons.
They are made of subatomic particles (APEX)

Number of protons in the nucleus is the atomic number.
The number of protons is equal to the atomic number of a chemical element.
Gold has 79 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a gold isotope = Mass number - 79
Gold has 79 protons and electrons and also 118 neutrons.
They are made of subatomic particles (APEX)
Yes, both silver and gold are composed of subatomic particles. At the atomic level, they are made up of protons, neutrons, and electrons. These subatomic particles combine to form the nucleus and electron cloud of an atom, determining its chemical and physical properties.

No, from 80 years.
Number of protons in the nucleus is the atomic number.
The total number of subatomic particles in the nucleus
No, sodium is not a subatomic particle. Sodium is a chemical element with the symbol Na and atomic number 11. Subatomic particles are particles smaller than an atom, such as protons, neutrons, and electrons.
The number of neutrons is different for isotopes.
Protons are the subatomic particles represented by the atomic number of an element. The atomic number is equal to the number of protons in the nucleus of an atom, which determines the element's identity on the periodic table.
