Question #7c97b

Answer 1

Approximately the mass of the element.

Explanation:

The atomic mass number refers to the approximate total mass of one atom of the element.

That is, the total mass of the protons, neutrons, and electrons in the element.

Since electrons have like `1/1837` the mass of a proton/neutron, we usually don't have to consider them.

So, the total mass of an element is mainly the sum of the protons and neutrons.

You can find the mass numbers of elements on the periodic table, and they will usually be located at the bottom of the element's symbol.
