1s7 electronic configuration is not observed because it violates ans. Pauli’s exclusion principle Bohr’s theory Aufbau principle Hund’s rule
Question
Solution 1
The electronic configuration 1s7 is not observed because it violates the Aufbau Principle.
The Aufbau Principle states that electrons occupy the lowest energy level first and then move to higher energy levels. The first energy level (1s) can only hold two electrons. Therefore, a configuration of 1 Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
