text2nd row transition series are element after Krypton in fifth periods starting from Ytrium i.e. 4d series.

Q. What is the general electronic configuration for $2nd$ row transition series?

$[N e] 3 d^{1 - 10}, 4 s^{2}$

$[A r] 3 d^{1 - 10}, 4 s^{1 - 2}$

$[Kr] 4 d^{1 - 10}, 5 s^{1 - 2}$

$[X e] 5 d^{1 - 10}, 5 s^{1 - 2}$
