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.

∙ 14y agono it is not necessary because some atoms are present in isotopic form which have same atomic number but different mass number

Do elements in the same group have the same atomic mass?
No.
How atomic number better than atomic mass?
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.
Is the atomic radius the same as the 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
How do you calculate the atomic mass of carbon?
The same way you calculate the atomic mass of other elements.
What is the difference between isobar and isotope?
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
Do elements in the same group have the same atomic mass?
No.
How atomic number better than atomic mass?

Is the atomic radius the same as the 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
Do elements in the same group have similar atomic numbers?
No. Elements in the same group have same number of valence electrons.
How do you calculate the atomic mass of carbon?
The same way you calculate the atomic mass of other elements.
What is the difference between isobar and isotope?
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
What is the atom with same atomic number but different mass number?
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.
Why is atomic number better than atomic mass for organizing the elements in the periodic table?
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.
Do transition elements follow the same trend of atomic radius as the main group elements?
NO
Do the elements in a row on the periodic table have the same average atomic mass?
no.
What trends in the elements properties do you notice about elements that are in the same group?
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
Is atomic mass and molar mass similar and mass number of particles the same?
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.
