Orbital Filling | MCQs

Explanation

When the 6d orbital is completely filled, the next electron enters the 7p orbital.

This is based on the Aufbau principle, which dictates that electrons first occupy the lowest energy levels available.

After the 6d orbitals (which can hold up to 10 electrons) are filled.

The 7p orbitals (which can hold up to 6 electrons) become the next lowest energy.
