How does the electronic configuration in atoms change in a period from left to right?

Open in App

Solution

Change in the electronic configuration in a period from left to right:

In a period, the number of shells remains the same but the number of valence electrons increases from left to right.

Therefore, the electronic configuration increases by 1 from left to right in a period.
