Hydrogen, because it has one proton and no neutrons, thus has an Atomic Mass of 1, and is element 1.
The same as its atomic number.
No, the atomic number is the number of protons that an atom contains. Atomic weight is the number of protons and neutrons.
Elements have the same number of protons in each atomic nucleus.
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
though your question is unclear, each element has its own atomic number. every sample of Sulfur (S) that exists has the atomic number of 16. No different elements share the same atomic number.
Atomic weight is not the same as atomic number for any element except hydrogen; this is the only element that has a radioactively stable isotope with no neutrons.
When two elements have the same atomic number, it means they are isotopes of each other. Isotopes have the same number of protons but different numbers of neutrons in their nuclei. This results in subtle differences in their atomic mass and stability.
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.

The atomic weight of any given isotope of an element is the result of the protons and the neutrons. The number of protons is the same as the atomic number, so if you subtract the atomic number from the atomic weight, voila, there is the number of neutrons. Bear in mind that elements have more than one isotope, and each isotope has a different number of neutrons. So the atomic weight is the result of a mixture of isotopes that appear in nature.
No, the atomic number is the amount of protons it has and the weight is its mass
Atomic number is unique. It cannot be same for different elements.
