Look at your Periodic Table of the elements. The number appears in every box. In addition, you can just count the elements, starting with hydrogen as element #1. The atomic number is the same as the numerical sequence that you get by counting the elements (but don't leave any out; remember that the lanthanide and actinide sequences are positioned outside of the rest of the array).

Atomic Mass minus atomic number
How do you find the number of neutrons in an elements atoms?
number of neutrons = mass number - atomic number
An atoms atomic number is the number of what in its nucleus?
atomic number
Is the atomic number the number of atoms it has?
The atomic number is equal to the number of protons.
What does one determine an atoms atomic mass?
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.
Do you count neutrons to find an atoms identity?
If by its identity you mean its atomic number, no. Neutrons only count towards the Atomic Mass Number, or AMU.
Who find that atoms with same atomic number but different atomic mass?
Isotopes are atoms with the same number of protons (atomic number) but different numbers of neutrons, resulting in different atomic masses. These isotopes have similar chemical properties but may have different physical properties due to their different masses.
Which number is the atomic number?
the number of protons in an atoms nucleus is called atomic number
What is number of protons of an atom is the atoms atomic number?
The number of protons in the atomic nucleus is equal to atomic number.
What does an element's atomic number stand for?
Atomic number is the number of protons in the atomic nuclei of the atoms of an element.
How do you find neutrons in an element?
In order to find the number of neutrons in the atoms of an element, you must specify the isotope that you are interested in. Isotopes are specified according to their mass number. For example carbon-12 is the isotope of carbon that has a mass number of 12, and carbon-14 is the isotope of carbon that has a mass number of 14. All atoms of the same element, regardless of mass number, have the same number of protons, which is the element's atomic number. To determine the number of neutrons in an isotope, you subtract the atomic number from the mass number. For example, the atomic number of carbon is 6, which means that all carbon atoms contain 6 protons in their nuclei. So, to find the number of neutrons in a carbon-12 atom, subtract 6 from 12, and you get 6 neutrons in the atoms of carbon-12. To find the number of neutrons in a carbon-14 atom, subtract 6 from 14, and you get 8 neutrons in the atoms of carbon-14.
