The radius of the second Bohr orbit, in terms of the Bohr radius (a 0 ) , of L i 2 + is given as x a 0 y . Find the sum of x + y here?

Correct answer

7

Step-by-step solution

We know r = 0.529 × n 2 Z Å r = a 0 × n 2 Z n = 2 Z = 3 r = a 0 × 4 3 = 4 a 0 3 Hence x = 4 , y = 3 So, sum of x + y = 4 + 3 = 7
