Multiple choice

If ' r ' is the radius of first orbit , the radius of nth orbit of the H - atom will be ?

  1. r n .

  2. r n2 .

  3. r / n .

  4. r2 n2 .
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This option is correct because radius of nth orbit is given by , r n= ( 0.529 n2 ) / Z . Radius of first bohr's orbit is , r  =  0.529 . Hence, radius of nth orbit will be = r n2 . Hence, this option is correct  .
