neutrons and protons
If you mean "how does one determine an atoms atomic mass?", then the answer would be to find a periodic table of elements where the whole numbers indicate atomic number and the other indicating atomic mass. Atomic number is generally described as the number of protons in a naturally occurring atom of a given element, and the atomic mass is the number of protons + number of neutrons in an atom.
The atomic number is the number of protons in an atom's nucleus. Given an atomic mass of 201, this information alone does not provide the atomic number as different elements can have the same atomic mass due to isotopes. More specific information about the element is needed to determine the atomic number.
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
By Atomic Mass
Gold is a meta element. Atomic Mass of it is 197.

Differences in mass can be attributed to variations in the number of particles or molecules present in a substance. This discrepancy in mass can arise from factors such as atomic weight, density, and composition of the material. The fundamental properties of the elements or compounds involved ultimately determine the mass disparity.
To determine the molar mass of an element, you must know the atomic mass of the element, which is found on the periodic table and is measured in atomic mass units (amu). This value represents the average mass of all the isotopes of that element.

Given an atomic mass of 201, this information alone does not provide the atomic number as different elements can have the same atomic mass due to isotopes.

Generally the term "atomic mass" is used for isotopes. For elements is preferred now "atomic weight".
To determine the mass of an element in a compound, you can use the chemical formula of the compound and the atomic mass of the element. Multiply the atomic mass of the element by the number of atoms of that element in the compound, then add up the masses of all the elements present in the compound to find the total mass.
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
By Atomic Mass
The molar mass of a compound is the sum of atomic weights of the contained elements in the molecule.The expression atomic weight is correct for elements; for isotopes is correct atomic mass.
Gold is a meta element. Atomic Mass of it is 197.

Dmitri Mendeleev, a Russian chemist, determined that atomic mass alone did not determine the pattern of the periodic table. He organized the elements based on their properties and predicted the existence of undiscovered elements based on the periodic trends he observed.
