1.Calculate the orbital radius of the hydrogen atom for the second principal quantum number.
2.Calculate the orbital radius of the hydrogen atom for the fifth principal quantum number.
3.Assume that the radius of the hydrogen nucleus is 1.4 · 10-15 meters. How much larger than the nucleus is the entire hydrogen atom? (Calculate the atomic radius for n = 1. Round answer to nearest tenth.)x 10 times larger than the nucleus.
4.Calculate the orbital radius of the hydrogen atom for the first principal quantum number. Use the general expression given in the test to calculate this value.
5.Calculate the speed of an electron in the innermost orbit of a hydrogen atom.
