The Ratio Of Radii Of 2nd, 4th And 6th Orbit Of Hydrogen Atom Is i) 2 : 4 : 6 ii) 1 : 4 : 9 iii) 1 : 4 : 6 iv) 1 : 3 : 2

Dear Student,

Atomic number of hydrogen Z = 1

The radius of nth orbital is rn=0.529n2 Ao

for the orbital 2, 4 and 6 we get,

r1:r2:r3 = n12 : n22 : n32 = 22 : 42 : 62 = 4 : 16 : 36 

on simplification we get 1 : 4 : 9

Hence the answer is Option (ii) 1 : 4 : 9

Regards.
