every thing would be proportionately larger than they are now
1 km
Because the size of an atom is about 100-500 nm, while the size of the nucleus is about 0.001 nm. In other words, the nucleus is from to 10 000 to 50 000 times smaller than the atom in which it resides. By analogy, the size of a marble of 1 cm can be compared to the size of a stadium of 100-500 m
What size marble? And is it made of marble or glass?
it would the size of a beachball

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.
The atom itself would be the size of an NFL stadium.
The electrons are repelled by the protons, which causes then to be farther away. If the nucleus was the size of a marble, then the atom would be the size of a football stadium. Correction: Electrons are not repelled by the protons but are attracted to them. Opposite charges attract.

Not all marble blocks are the same size.
The mass of a regular size marble is 1.27 grams.

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).
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.
