Question

the elements having atomic no 90 is this element dimaganetic and pramagnetic​

Answer 1

Answer:

Explanation:

The electronic configuration of element with atomic number = 90 is [Rn] 5f0 6d2 7s2 . There are two unpaired electrons in the 6d orbital of the element. Hence, it is paramagnetic.

Answer 2

The Configuration of element having atomic number = 90 is [Rn] 5f0 6d2 7s2 .
Two unpaired electrons are there in the 6d orbital of the element. So ,it is paramagnetic.
