The radius of the first orbit of hydrogen atom is 0.52 xx 10^(-8) cm. The radius of the first orbit of He^(+) ion is 0.26 xx 10^(-x)cm. Then the value of x is _______

The radius of the first orbit of hydrogen atom is 0.52 xx 10^(-8) cm.

1.	The radius of the first orbit of hydrogen atom is 0.52 xx 10^(-8) cm. The radius of the first orbit of He^(+) ion is 0.26 xx 10^(-x)cm. Then the value of x is _______
Answer» SOLUTION :`r= (0.52xx10^(-8) xx 1^2)/(2) = 0.26xx10^(-8) cm`
