Question

$X-K_{\alpha }$
$Y-K_{\beta }$
$Z-K_{\gamma }$

• A. 1-x, 2-y, 3-z
• B. 2-x, 1-y, 3-z
• C. 3-x. 2-y, 1-z
• D. 1-x, 3-y, 2-z

Answer 1

The correct option is A 1-x, 2-y, 3-z

This is a definition based question.
We defined as following :

$K_{\alpha }$ : When electronis transition takes place from L-shell to K-shell or vacancy shifts from K-shell to L-shell (this is what the energy level diagram indicates)

$K_{\beta }$ : When electronis transition takes place from M-shell to K-shell or vacancy shifts from K-shell to M-shell (this is what the energy level diagram indicates)

$K_{\gamma }$ : When electronis transition takes place from N-shell to K-shell or vacancy shifts from K-shell to N-shell (this is what the energy level diagram indicates)

Got the answer!!
