Question

As the orbit number increases, the distance between two consecutive orbits in an atom or ion having single electron

• A. increases
• B. decreases
• C. remains the same
• D. first increases and then becomes constant

Answer 1

The correct option is A increases

We know, $r\propto \frac{n^2}{Z}$

Distance between two consecutive orbits $\propto n^2-(n-1{)}^2$ = $2n-1$
So as n>0, when the orbit number increases, the distance between two consecutive orbits in an atom or ion having a single electron, increases.
