In fact it's MUCH smaller. Atoms are mostly empty space, as is all of matter.
Remember that the concept of 'atoms' is only a model, no doubt soon to be swept away by a newer, sexier 'model'.
In other words, the more we know, the less we know we know.

it somewhat is by using fact the electrons make a contribution the main to the size of an atom yet carry little or no mass (some thing like a million/2000 of that of a neutron of proton which make up the nucleus)

There is a lot of empty space between the nucleus and the electrons in the atom. The number of protons is equal to the number of electrons and the number of neutrons is about the same as the number of protons. Protons and neutrons each have about 1836 times the mass of an electron, so the mass of the nucleus is about 3672 times the electron mass.

A proton and a neutron is 1840 times the mass of of an electron.
There could not be more than 110 electrons in an atom. Less than 10% of the mass of 1 proton.

Because the nucleus contains the neutrons and protons. They contain the weight of most of the atom. The electrons that orbit the nucleus weigh next to nothing in comparison.

because the in the rest of the atom there is a lot of empty space that has no mass. There is a large volume compared to the nucleus, yes, but the mass is smaller. Did that make sense?

A proton is 1800 times more massive than an electron. Since the protons and neutrons are essentially equal in mass, the much smaller electrons don't count in the mass of the atom.

heres my drawing of an atom mass wise
the nucleus is where most stuff is, but area around the nucleus where theres a bunch of lil tiny electrons floating around is still considered part of atom

The mass is needed in the center to keep the orbiting electrons from just flying away.
