Question

When a 4 p orbital is completely filled then the next electron goes to

Short answer

Answer: The next electron goes to the 5s orbital after the 4p orbital is completely filled.

Step-by-step solution

Understand the electron configuration order following the Aufbau principle

According to the Aufbau principle, electrons fill orbitals from lowest energy to highest energy levels. The order of filling is: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, and so on.

Identify the position of the 4p orbital in the filling order

Based on the order of electron filling mentioned in step 1, we can see that the 4p orbital is the 8th type of orbital in the sequence.

Determine the next orbital for the electron to occupy

By referencing the electron filling order, we can find the next orbital after the 4p orbital. In this case, it is the 5s orbital. Thus, after the 4p orbital is completely filled, the next electron goes to the 5s orbital.
