What atom has the following orbital-filling diagram?

Video transcript

Hello everyone today. We have the following question. Consider the following orbital filling diagram identify the element. So here, seeing that we have this noble gas here in a brackets. We see that this is going to be a condensed electron configuration where the core figuration of the element is neon and therefore our principal quantum number or in for sure is going to represent our energy orbital level that we are at. And so we see here that we are in the third energy level. So that's going to be period three. So we're gonna hang on to that information for a little bit. We also know that the three p shells incomplete and that the total number of the total valence electrons total is going to be the two that we have here in our s orbital plus the one that we have in our three s orbital. And so this is going to indicate that we have three Valence electrons. And so what does this mean? This means that our element belongs to group three a or three for short. And so, using these two pieces of information, we can denote that our element in question is going to be aluminum or a L for short. And with that we have answered our question overall, I hope that this helped and until next time
