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.
no atomic radius is not the same as atomic mass because it is 10 to the power of 10 and atomic mass is different for different elements
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)
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.

No. Elements in the same group have same number of valence electrons.

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.

NO
They have the same valency. The atomic radius of elements increases by one as you go down the group. They also have the same properties
no.

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.
