Which of the following statements is true of hydrogen atom ?

Options

A. Angualr moment `prop(1)/(n)`
B. Linear moment `prop(1)/(n)`
C. Radius `prop (1)/(n)`
D. Energy `prop (1)/(n)`

Answer

B

Explanation

Angular momentum `L=mvr=(nh)/(2pi)` or `mv=(nh)/(2pi)`
Now, `rpropn^2`
`therefore mv=pprop(nh)/(2pixxn^2)rArrpprop(h)/(2pin)` or `pprop(1)/(n)`
Energy, `Eprop(1)/(n^2)`
