it depends on the atom! For Hydrogen the atomic size could be described as '1' as it is the first atom and has 1 proton, 1 neutron and 1 electron. Then helium would be 2 and so on. Though we tend to use the size of the carbon atom to make relevent sizes to every other atom.
That would be Thomson
it would the size of a beachball
Atoms of any size are much too small to see, because an atom is smaller than the wavelength of any light visible to humans; therefore, it doesn't "look like" anything. The atom described in the question is an atom of the isotope carbon-12.
The same size as it is in a Helium atom

The atom itself would be the size of an NFL stadium.

It’s the most massive part of the atom
atom was described as tiny, hard, indestructible sphere by Newton.

If the electron were the size of a golf ball, the proton would be about the size of a basketball and the electron would be orbiting about 8000 meters away (assuming the Bohr model of the atom).
It was commonly described as a Solid sphere
By the size of the atom and its mass
In the nucleus of the atom, along with neutrons. The electrons are found around the nucleus. If the atom was the size of a Baseball stadium, the nucleus would be the size of a baseball! Most of the space in an atom is taken up by the electron cloud which surrounds the nucleus. That is why atoms are actually mostly empty space.
The number of protons in the atom's nulceus.
