Question

in an elements square on the periodic table, the number with the greatest numerical value represents the
number of neutrons.
number of electrons.
atomic number
atomic mass.

Explanation:

On the periodic table, the atomic mass is the weighted average mass of an element's isotopes. It is calculated considering the relative abundance of each isotope. The atomic number represents the number of protons. The number of electrons (in a neutral atom) is equal to the atomic number. The number of neutrons is calculated as \( \text{Neutrons}=\text{Atomic Mass}-\text{Atomic Number}\). Since atomic mass is a weighted - average mass (and usually has a non - integer value for many elements, while atomic number is an integer), among the given options, the number with the greatest numerical value in an element's square on the periodic table is the atomic mass.

Answer:

atomic mass.
