Help With A Chemistry Problem?

Question

If you wanted to make an accurate scale model of the hydrogen atom and decided that the nucleus would have a diameter of 1 mm, what would be the diameter of the entire model?

PLEASE HELP!!!

Answer 1

The diameter of a proton is on the order of 1 femtometre, that's 1 * 10^-15 metres.

The diameter of a hydrogen atom is on the order of 0.1 nanometre, that's 1 * 10^-10 metres.

Therefore the size of a hydrogen atom is 10^5 times the diameter of the nucleus. So for the model, since 1 mm is 10^-3 metres, the diameter of the atom would be 10^2 metres, or 100 m.

Answer 2

1mm for nucleus..1mm gap and then 1mm for electron since the first isotope of hydrogen Protium has no neutrons

Answer 3

Go to this site and scroll down until you see "atomic radius" on the right side.  Click on the blue link and it will give you quite a bit of information on the size of the hydrogen atom.  It's pretty small so you will have to make conversions.  Try using stiochiometry and that should make it fairly simple.  Good luck.
