Question

An element with configuration [Arg]3d2 4s2 belongs to A. D- block B. p-block C. S- block D. f- block

Answer 1

[AR]3d2 4s2 belongs to d block.

Answer 2

Heya..!

here's your answer..!

we can predict the block to which an element belong to by observing the differentiating electron's entry..
(The differentiating electron is the last electron that is added when you are writing the electronic configuration.)

here, differentiating electron is entering into d orbital..


[hint: d orbital is incompletely filled. so, differentiating electron must enter d orbital only.]

so, the element belongs to d block.
