Proton number, which is an element's atomic number, identifies an element. Each element has a unique atomic number (number of protons).
The number of protons of an element indicates its atomic number. The atomic number, in turn, is the unique identifier that is used to name an element.
This particle is the proton which is equal to the atomic number.
Helium, number two on the periodic table of elements. Nothing else has two protons, for to remove a proton or add a proton is to change the element.
Elements as H, He, Li, Be, B, C, N, O.
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
The number of protons is different for each element, but the mass of each individual proton is always the same.
Proton number
equal
it means no of proton in its nucleus which is the identity of an atom.
This particle is the proton which is equal to the atomic number.
The number of protons in the nucleus of an atom determines the identity of the element.
You need to clarify this question. Do you mean, "How is the number of protons determined in the periodic table of the elements?"
Periodic table
Iodine has 53 protons.
Helium, number two on the periodic table of elements. Nothing else has two protons, for to remove a proton or add a proton is to change the element.
Henry Mosely
Elements are listed by the number of protons they contain starting with Hydrogen which has one proton.
Elements as H, He, Li, Be, B, C, N, O.
