Answer
In the nucleus
Explanation
## Step 1:The mass of an atom is primarily concentrated in its nucleus. The nucleus of an atom contains protons and neutrons.## Step 2:Electrons, which orbit the nucleus in electron shells, have much less mass. They are so small that their mass is often considered negligible when calculating the atomic mass.## Step 3:For example, the atomic mass of indium is 114.818 unified atomic mass units (u). This mass is almost entirely due to the protons and neutrons in the nucleus. Electrons contribute negligibly to the overall mass.
