Question

An electron jumps from $6^{th}$ shell in an hydrogen atom, the number of Lyman emission lines will be:

• A. 5
• B. 6
• C. 10
• D. 12

Answer 1

The correct option is A 5

From level 6 to level 1 i,e,

$6\to 1$

and $5\to 1$

$4\to 1$

$3\to 1$

$2\to 1$

So total 5 lines in Lyman series.
