Answer» ong>Answer: An element can have differing NUMBERS of neutrons in its NUCLEUS, but it always has the same number of protons. The versions of an element with different neutrons have different masses and are called isotopes. The average atomic MASS for an element is calculated by SUMMING the masses of the element’s isotopes, each MULTIPLIED by its natural abundance on Earth. When doing any mass calculations involving elements or compounds, always use average atomic mass, which can be found on the periodic table. |
