Question

What is the velocity of electron moving in 2nd orbit of hydrogen atom

Open in App

Solution

Velocity of Hydrogen atom => Z / n

Z = atomic number

n = orbit / number of shell

velocity = K × Z / n

=> K = 2. 08 × 10 ^ -18

K = constant of proportion

because V directly proportional to Z and inversely proportional to n

=> velocity =. k × 1 / 2

=> 2.8 × 10^ -18 /2

=> 1.4 × 10^ -18
