Question

As the principal quantum number increases, the difference of distance of separation between consecutive energy levels:

• A. decreases.
• B. remains the same.
• C. increases.
• D. some times increases and sometimes decreases.

Answer 1

The correct option is C increases.

$r=0.529\frac{n^2}{Z}A°$ i.e., $r\propto n^2$

$\therefore$ As the principal quantum number increases, the difference of distance between $2$ consecutive energy level increases.
