If the velocity of electron of Hydrogen present in second shell is x m

1.	If the velocity of electron of Hydrogen present in second shell is x m/s, then calculate velocity of electron of He+ revolving in 2nd shell in terms of x.
Answer» Velocity at nth orbit is v= (2.165 x10⁶) x (Z/n) actually v= (2( π²)Km(e²)Z )/(hn) K= electrostatic constant m= mass of electron e= charge of electron h= planks constant n= nth orbit Z= atomic number this simplifies to the top expression so for 3rd orbit of hydrogen v= (2.165x 10⁶ )/ 3 v= x/3 ⃗Vₙ = v₀ × z/n Vₙ is the velocity in the nth orbit. Z is atomic number. V⃗₃ = v⃗₀× 1/3 V⃗₃ = x/3

If the velocity of electron of Hydrogen present in second shell is x m/s, then calculate velocity of electron of He+ revolving in 2nd shell in terms of x.

Answer»

Velocity at nth orbit is v= (2.165 x10⁶) x (Z/n)

actually v= (2( π²)Km(e²)Z )/(hn)

K= electrostatic constant

m= mass of electron

e= charge of electron

h= planks constant

n= nth orbit

Z= atomic number

this simplifies to the top expression

so for 3rd orbit of hydrogen

v= (2.165x 10⁶ )/ 3

v= x/3

⃗Vₙ = v₀ × z/n

Vₙ is the velocity in the nth orbit.

Z is atomic number.

V⃗₃ = v⃗₀× 1/3

V⃗₃ = x/3
