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.
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 2kg is closest to 2020g because it is the only number that can work for this answer.
The atomic number, or Proton number, defines which element it is. So by definition, two different elements must have a different atomic number, or else they'd be the same element. Atomic mass is the number of protons + neutrons in the element's nucleus. Since the number of neutrons in the nucleus can vary, even within a single element (as isotopes) it is possible to have one isotope of one element sharing an atomic mass with an isotope of another element.

When two elements have the same atomic number, it means they are isotopes of each other. Isotopes have the same number of protons but different numbers of neutrons in their nuclei. This results in subtle differences in their atomic mass and stability.
The atomic mass of an isotope is the sum of protons, neutrons and electrons masses.
only one element (hydrogen) has the atomic mass of 1.
Atomic mass and Atomic number
Two elements can have the same atomic mass if one has more or less neutrons than protons in the nucleus. These are called isotopes. not much to im prov thank you
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.)
Not generally. For light elements this relation is often approximately true, but for heavier elements, the gram atomic mass is more than two times the atomic number, as the ratio of neutrons to protons increases with increasing atomic mass.
