Question

The electronic configuration of an element is 1s22s22p63s23p63d54s1.this represents its ? a)excited state b)ground state c) cationic form d) anioinic form.

Answer 1

Answer:- b)ground state Explanation:- The electronic configuration of the element is  1 s 2 2s 2 2 p 6 3 s 2 3 p 6 3 d 5 4 s 1 We can see that the above electronic configuration is obeying aufbau principle as well as hund's rule of maximum multiplicity.  As such it is neither excited state or nor cationic form or anionic form. It is thus the ground state electronic configuration of the element.

Answer 2

Answer: (option b) Ground state

Explanation:

As this configuration of electrons belongs to Cr

So according to the Hands rule it belongs to the ground state .

Hope this will help you
