What is the next atomic orbital in the series 1s, 2s, 2p, 3s, 3p, 4s1 point4p4d3d3p

The next atomic orbital in the series 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p would be 5s.

Here's the step by step explanation:

1. The atomic orbitals follow a specific order of filling which is determined by the Aufbau principle. This principle states that electrons fill the lowest energy levels first, and then move on to higher energy levels only after the lower ones are full.

2. 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.

3. Each orbital can hold a certain number of electrons: s can hold 2, p can hold 6, d can hold 10, and f can hold 14.

4. So, after 4p, the next orbital to be filled is 5s.
