if the speed of electron in Bohr's first orbit of hydrogen atom is x,the speed of the third orbit is
Hey,
What we know it the velocity of electron is (2.18*10^6*z)/n where n is orbit number and z is the atomic number of the element.
Now, we know that the value of atomic number of hydrogen is 1 and velocity is inversely proportional to n therefore if the speed of first orbit is x then for third it will be x/3.
I hope this helps.
All the best!
Hello Hani,
We know that velocity of electron is given as -
v= (2.18×10^6× z) / n
Where,
n= no. of orbit
z= atomic no.
v= velocity
Since we have hydrogen atom we fix z= 1
If, for orbit 1 velocity is x, so for orbit 3 velocity is x/3.
HOPE THIS WILL HELP YOU
GOOD LUCK!

Hi,
The velocity of an electron is z x e^2 / 2nh.
For the first orbit: v= 1 x e^2 /2 x 1 x h ==> v=e^2/2h which is equal to x
For third orbit v= x/3
Hope this helps!
hello aspirant
well for that you need to know the formula for velocity of an electron
which is v=(2.18∗10power6∗z)/n
where each letter denotes something like n=orbit no
z=atomic no
v=velocity
so as we take hydrogen atom where z=1
so for orbit 3 it is x/3
