Question

the velocity of an electron moving in 3rd orbit of He+ is v the velocity of electron moving in 2nd orbit of Li+2 is​

Answer 1

Answer:

velocity is directly proportional to Z/N where Z is atomic number and N is principal quantum number or orbit number and here in this case velocity does not depends on mass

Explanation:

V he / V Li = Z he x N Li  / Z Li  x  N he

V he / V Li = 2  x  2  /   3 x  3

V he / V Li  =  4 / 9

V / V Li = 4/9

V Li  = 9v/4
