What's Covered in the Video:
Imagine trying to make a perfect sandwich by balancing just the right amount of bread and filling. Similarly, the mass number of an atom is like this perfect sandwich, where the bread represents protons and the filling represents neutrons. Just as the sandwich's overall weight depends on the right combination of bread and filling, an atom's mass number is determined by the sum of its protons (bread) and neutrons (filling) in the nucleus.
