1) Assuming the diameter of the circle represents a proton, calculate the relative distance of the electron from the proton in a hydrogen atom. Show your calculation in the space below.

2) Roll out a length of yarn to reflect the length you just calculated; this will illustrate the relative distance of the electron from the proton.



3)What can you conclude when comparing the size of the proton with the distance of the electron from the proton?

4)Measure the diameter of a pea with the metric ruler and record this value.

5)Assuming the diameter of the pea represents a proton, calculate the relative distance of the electron from the proton in a hydrogen atom.









6)What do you think lies between the proton and the electron in a hydrogen atom?







7)s the electron always in one spot in a hydrogen atom, or does its position change?

Answer 1

Answer: For 1 is The diameter of a proton is 1.75× 10-15lm. The Bohr radius — the most probable distance from the nucleus to the electron — is 5.29 ×10-11lm. The diameter of a hydrogen atom is therefore 2 × 5.29 ×10-11lm = 1.058 ×10-10lm.
