Question

calculafirst.te the velocity of electron in bhor orbit of hydrogen atom . give that bhor radius =6.626×10^-31kg and 1j= 1kgm^2 s^2​

Answer 1

Answer:

Velocity of electron in first Bohr orbit of H- atom

mvr=2πnh, r=a0=0.529Ao

n=1,h=6.626×10−26,m=9.1×10−31kg

∴v=2π×91×10−31×0.529×10−101×6.626×10−26

=2.18×106ms−1.
