Question

according to the bohr model of the hydrogen atom, what is the closest an electron can get to the nucleus? What is the farthest it can get from the nucleus? ( if the latter answer seems absurb, it might amuse you to know that it is the same value predicted by present-day quantum chemistry)
I am having a hard time to answer this please someone help. I search for th answer but I can't find it in my book

Answer 1

The closest is n = 1 shell.
The farthest is infinity.

Answer 2
