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.
Do all elements in the same group have the same atomic mass?
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.
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 two elements have the same atomic mass?
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.

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.

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 the elements in a row on the periodic table have the same average atomic mass?
no.
Do transition elements follow the same trend of atomic radius as the main group elements?
NO
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.
Which 2 elements in period 6 have the same relative atomic mass?
In period 6, the two elements that have the same relative atomic mass are lead (Pb) and thallium (Tl), both of which have an atomic mass of approximately 204.37 u. Their similar atomic masses can lead to some confusion, but they are distinct elements with different properties and uses in chemistry and industry.
How does the number of valence electrons vary as the elements within the group increase in mass?
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.
