Example: the atomic mass number of uranium is 238,02891 - exprimed in atomic mass units.
Look on the Periodic Table. The bottim number is the Atomic Mass and the top is the atomic number. ex. The atomic mass for O (oxygen) is 16.
atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number
well you look at the periodic table of elements. the atomic number equals the number of protons. Then subtract the number of protons from the atomic mass (both protons and nuetrons have atomic mass units of 1 and electrons equal 0). That will give you the number of nuetrons.
83.98 amu is the Atomic Mass, 36 is the atomic number.
No, the atomic mass is not equal to the atomic number. The atomic number represents the number of protons in an atom's nucleus, while the atomic mass is the sum of protons and neutrons in the nucleus. The atomic mass can differ from the atomic number, especially due to the presence of neutrons.

The atomic mass of an element is average of the number of protons in an atom plus the number of neutrons. For example, if you look at a periodic table of elements, Hydroge has the atomic mass of 1.0079.
Mass number: 14 Atomic/proton number: 7 If you look at the periodic table, the mass number is the top and the atomic number is the bottom number.
To determine the number of protons, look at the atomic number. The number of electrons is also the atomic number.To find the number of neutrons subtract the atomic number from the Atomic Mass number.
It is impossible to determine the number of neutrons from the mass number and atomic mass, since the two are essentially same value. However, with the atomic number and the mass number, one can calculate the number of neutrons by subtracting the atomic number from the mass number.

You have to know the element with the mass number of 75. Then you would look it up on the periodic table to find the atomic number, which is the number of protons.
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
