For an electron in successive Bohr orbits of hydrogen, which quantities increase as $n$ increases from 1 to 4?

AKinetic energy of the electron
BRadius of the orbit
CSpeed of the electron
DTime period of revolution

Answer: B, D

r \propto n^{2}

and

T \propto n^{3}

increase.

v \propto 1/ n

and

KE \propto 1/ n^{2}

decrease.
