Where on the blank outline of the periodic table do elements that meet the following descriptions appear? (c) Elements with electrons whose largest principal quantum number is n = 4

Video transcript

Hello everyone today we are being asked, referring to the sketch of the periodic table shown below, which among the highlighted elements contains electrons whose highest principle quantum number in is equal to five. So essentially Our quantum number equaling five means that this is going to be in the 5th period and periods are going to be horizontal from left to right. So if we count from the first row 12345, the only electron in that row is C. And so that's actually going to be our answer. See overall, I hope that has helped and until next time.
