Question

which rule is violated in the electronic configuration 1s^0 2s^2 2p^4​

Answer 1

Answer:

In the given electronic configuration, the first sub-shell doesn't contain any electrons while they have started filling from the next sub-shell. This violates the aufbau's rule which states that electrons must start filling from the shell with lowest energy.

The Correct Electronic Configuration is = 1s² 2s² 2p²

I hope this helps.
