Question

plz tell me the ans?

Answer 1

radius of hydrogen atom in nth radius = 0.529 n^2
substituting in the formula :
radius of first orbit = 0.529 (1)^2 = r1
radius of second orbit = 0.529 (2)^2 = r1 (4) = 4r1
radius of third orbit = 0.529 (3)^2 = r1(9) = 9r1
radius of fourth orbit = 0.529 (4)^2 = r1(16) = 16r1

Answer 2

Radius of any Hydrogen like species is given by r=0.529(n^2)/Z where n is the orbit number and Z is the atomic number of the element whose radius is to be measured.
Now according to ur case
