Question

1) An element with atomic no. 24 belongs to - a) s-block b) d-block c) f-block d) p-block.

Answer 1

Answer:

d block(transition element)

Answer 2

Answer:

(b) d-block.

Explanation:

The electronic configuration of the element whose atomic number is 24 is 1s²2s²2p6 3s²3p6 4s¹3d5. From the electronic configuration, we find that this element i. e. whose atomic number is 24, belongs to 'd - block' because this element receive the last electron in 3d orbital hence, it belongs to d-block.
