Calculate the K.E. and P.E. of electron in the first orbit of hydrogen atom. Given `e =1.6 xx 10^(-19)` C and `r = 0.53 xx 10^(-10)` m.

Text Solution

Verified by Experts

`e=1.6 xx10^(-19) C`
Radius =r =`0.53 xx10^(-10) m`
K.E of electron in first orbit of hydrogen
P.E of electron in first orbit of hydrogen atom =`P.E=(1)/(4pi epsilon_(0)) (e^(2))/(r )`
`=-2xx13.58 =-27.16 eV`
