What is the radius of Li 2+ ion in 2nd orbit and please give me the formula

```
4 years ago

```							@ piyush 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 / 3and u will get the answer . HOPE IT CLEARS YOUR DOUBT ALL THE BEST ..

```							The formula of finding the radius of atom = 0.529 * n^2/ZSo, here the ‘n’ is 2 & ‘Z’ is 3Then, Radius=0.529 * 4/3                   =0.705

```							Formula For the radius is- n^2/Z×0•529×10^-10mIn this question,Z=3,n=2Using formula4/3×0•529×10^-10=0•7053×10^-10✓✓✓Best Of Luck✓✓✓

```							Dear StudentAs we know,rn​= r1 for H × n2/Z= 0.529A×n2/Z​r2​for Li2+= 0.529A×22/3​= 0.529A×4​/3 A0I hope this answer will help you.Thanks & RegardsYash Chourasiya
