The atomic number is the number of protons. For example, the atomic number of Hydrogen is 1, because it has 1 proton. The mass is calculated using protons, neutrons, and electrons.

Is the atomic mass and number the same thing?

No, the atomic mass consists of protons, but the atomic mass consists of both protons and neutrons.


What is the atomic mass the same as?

The Atomic Mass is equal to the number of protons and electrons that an element has.


Is the atomic number and atomic mass the same?

No, the atomic number is the amount of protons it has and the weight is its mass


Is atomic mass and atomic number the same thing?

No, atomic mass and atomic number are not the same thing. Atomic mass represents the average mass of an atom of an element, which includes the mass of protons, neutrons, and electrons. Atomic number, on the other hand, represents the number of protons in the nucleus of an atom, which also determines the element's identity on the periodic table.


Do protons and nuetrons have same atomic number?

no. -------------- In atoms, only the Protons count as atomic number The neutrons and the protons together is as the atomic mass


What is silvers atomic mass?

actually the atomic mass is the same as the amount of protons so if you want to be lazy here are the atomic number (in which is 47 also the same as the atomic mass) and the atomic mass 47, and the number of protons 47.


If the atomic mass of an atom is 48 and the atom contains 20 protons how many neutrons does the atom contain?

If the atomic mass of the atom is 48 and it contains 20 protons, then the atom contains 28 neutrons. This can be calculated by subtracting the number of protons from the atomic mass, since the atomic mass includes both protons and neutrons.
