Question
The velocity of electron in second shell of hydrogen atom is :
Options
A.10.94 × 106 ms-1
B.18.88 × 106 ms-1
C.1.888 × 106 ms-1
D.1.094 × 106 ms-1
Solution
According to Bohr, velocity (v) of an electron is given by relation.
v = 2.188 × 106
m/s
Here n =2,and Z(for H ) = 1
∴ v =
= 1.094 × 106 m/s
v = 2.188 × 106
m/sHere n =2,and Z(for H ) = 1
∴ v =
= 1.094 × 106 m/s
