The element with the greater atomic number will have a greater atomic mass. Atomic mass is the sum of the protons and neutrons in an atom's nucleus, and since the number of protons increases with atomic number, so does the atomic mass.
The atomic mass of magnesium is approximately 24.305 amu (atomic mass units).
The element is Iodine (I). It has an atomic mass of about 126.9.
The element with the highest atomic mass is Oganesson.
Chlorine (Cl) has the greatest atomic mass among lithium (Li), chlorine (Cl), and carbon (C) with an atomic mass of approximately 35.5 amu.
Element A has a greater atomic mass than element B if the atomic mass value of A is higher. The atomic mass represents the average mass of an element’s isotopes based on their abundance in nature.
