| 1 | So let's take the example of neon. | |
| 2 | In the first case, so here is the electron configuration of neon. | |
| 3 | We've got two cases where each one of those things now is isoelectric with neon. | |
| 4 | So, I've got something that's one electron away from the electronic structure of neon. | |
| 5 | The lamps of the gallery were full of gaseous neon, which made the light colorful. |
