WebFinding the Number of Neutrons. The number of neutrons in an atom can be calculated by subtracting the atomic number from the atomic mass. Both of these numbers can be found on the periodic table. The atomic number is listed above the symbol of the element whereas the mass number is placed below. Let’s keep using oxygen as our example.
WebChallenge: Think about the factors that control atomic radius and the patterns you’ve seen.A. Why does the atomic radius decrease as electrons are added to a shell because the protons areincreasingB.

This is the standard unit for atomic or molecular mass, and 1 amu is thus 1/12 th the mass of a 12 C atom. This is obviously very small. 1 amu = 1.66054x10-27Kg = 1.66054x10-24 g. hungry howies corporate officeWebThe mass number is approximately equal to the atomic mass, which is the mass of a single atom of a element measured in atomic mass units (amu).
