What’s the reIationship between an eIement's atomic mass and eIement's isotopes?

Isotopes of an element have the same number of protons but have different numbers of neutrons in their nuclei. The mass number is the sum of the numbers of protons and neutrons in the nucleus of an atom.

Explanation: I hope this helps

the maximum mass of nh3 is nh3 in grams

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
