Question

What would be the radius of 2nd excited state in li+2 ion? solution?

Answer 1

u haVE to use the below formula

r (n ) = n ^ 2*0.529* 10^ -10 / zm

z = atomic number = 3

n = 2 (as given 2nd orbit )

just put the value in the formula and calculate it .

r (n ) = 4 * 0.529* 10 ^ -10 / 3

and u will get the answer .
