Learning goal 1: The atomic number of neon is 10. Identify its electron configuration. 102.52.88.2

The electron configuration of an atom is determined by its atomic number, which is the number of protons in its nucleus. In the case of Neon, the atomic number is 10.

Here are the steps to find the electron configuration:

1. The first two electrons will go in the 1s orbital. The 1s orbital is the closest to the nucleus and the first to be filled. So, we have 1s^2 (2 electrons).

2. The next two electrons will go in the 2s orbital. So, we have 2s^2 (2 electrons).

3. The remaining six electrons will go in the 2p orbital. So, we have 2p^6 (6 electrons).

So, the electron configuration of Neon (atomic number 10) is 1s^2 2s^2 2p^6.
