Approximately all of the atom's mass is in the nucleus. The electrons contribute almost zero.
No atom has more than 100 electrons, but eachproton or neutron in the nucleus
has the mass of more than 1,800 electrons.
Most of the mass of a potassium atom is located in its nucleus, which contains protons and neutrons. The electrons in the electron cloud surrounding the nucleus have significantly less mass compared to the nucleus.
These particle are neutrons and protons; they are located in the atomic nucleus.
The nucleus.
More then 99% of an atoms mass is in the nucleus.

it represents where the atoms, protons, Atomic Mass, atomic number, and electrons where they are located on the nucleus.
The mass of an atom is concentrated in the nucleus (protons+neutrons).
Mass is not used as a method of counting atoms directly. Instead, the atomic mass unit (amu) is used to measure the mass of individual atoms relative to the mass of a carbon-12 atom. The mole is the unit used to count atoms, with 1 mole containing Avogadro's number of atoms.
