The Atomic Mass is grams/mole
So when you have e.g. 12 grams of carbon which has atomic mass = 12, you have one mole. ( Avogadro's number is one mole: 6.02×10²³ )
If the atomic mass of an atom is x, then the mass of 1 mole of the atoms is x gram.
Atomic mass is grams per mol. For instance if you have one mol of Oxygen and its atomic mass is 15.9994 g/mol, then you have 15.9994 grams of Oxygen.
The atomic number is the number of protons the element possesses.
Proton number, which is an element's atomic number, identifies an element. Each element has a unique atomic number (number of protons).
Atomic number: number of protons in a nucleus unique to an element Atomic mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.
The atomic number of a chemical element is identical to the number of protons.

The mole is the atomic weight expressed in grams.
The atomic number is the number of protons the element possesses.
A German chemist Dobernier observed relationship between atomic masses of several groups of three elements called traids.In these groups the central or middle element had atomic mass average to the other two elements.
Every elements has atomic number, elements identity determined the number of protons in its nucleus.
Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
Proton number, which is an element's atomic number, identifies an element. Each element has a unique atomic number (number of protons).
the atomic number is the number of protons in a certain element. elements are arranged on the periodic table by atomic number in increasing order
Atomic number: number of protons in a nucleus unique to an element Atomic Mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.
Atomic number: number of protons in a nucleus unique to an element Atomic mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.
The atomic number of a chemical element is identical to the number of protons.
Each isotope of an element has an atomic mass. The average of all the atomic masses of an element's isotopes gives an elements atomic weight. For this reason, atomic weights are decimal numbers.
