What else can I help you with?
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.
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)
Is the atomic radius the same as the atomic mass?
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.

Do elements in the same group have similar atomic numbers?
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.
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 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.
Is the atomic radius the same as the atomic mass?
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 atomic mass is the?
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.
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.
Can an atom of two different elements have the same mass number?
Yes. The mass number is basic to the different elements, even more useful than the atomic number. (Unless it is an isotope. Isotopes have a different amount of neutrons than the basic element atom which makes a difference in mass number too. So, a difference in mass numbers doesn't always mean it is a different element.)
What is the same about a atomie mass and atomie 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.
