No. Atoms of the same element can have different masses as the number of neutrons can vary.
Atoms of the same element but with different masses are called isotopes.
No.
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.
The same way you calculate the atomic mass of other elements.
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
Two elements that have the same atomic mass are isotopes of the same element, such as carbon-12 and carbon-14, which are both forms of carbon but differ in the number of neutrons. However, if you're looking for different elements with nearly identical atomic masses, chlorine (atomic mass ~35.45) and argon (atomic mass ~39.95) have values that can sometimes be confused due to their proximity on the periodic table, but they are not equal. In general, elements do not share the exact same atomic mass.

Elements in the same group have similar chemical properties but not necessarily similar atomic numbers. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical properties.

No, the atomic radius and atomic mass are not the same. The atomic radius refers to the size of an atom, typically measured as the distance from the nucleus to the outer electron cloud. On the other hand, atomic mass is the mass of an atom, which is the sum of the protons and neutrons in the nucleus.
The expression atomic mass is used only for isotopes; the atomic mass is the mass of an atom expressed in unified atomic mass units - (1 amu = 1/12 atomic mass of carbon-12).For elements the expression is atomic weight; the unit is the same.
As elements within a group on the periodic table increase in mass, the number of valence electrons remains constant because elements in the same group have the same electron configuration in their outer shell. For example, all elements in Group 1 have one valence electron, while those in Group 2 have two, regardless of their mass. However, the increasing mass generally corresponds to higher atomic numbers and additional electron shells, but the valence electron count does not change.
Atomic number is a unique number for each element. No two elements have the same atomic number. Atomic number is also the number of protons in the nuclei of the atoms of any given atom. Atomic mass, however, is the number of protons, neutrons and electrons. The number of neutrons can vary with different isotopes of the same element, this means that atomic mass can vary with different isotopes. So atomic number does not vary, but atomic mass does, so it is more logical to use atomic number to organize the elements. In addition, when the elements are arranged according to atomic number into seven rows and 18 columns, it becomes evident that there are certain trends that occur across the periods, and that elements in the same group have similar properties.
