In this question, we are to arrange calcium, rubidium, silicon, sulfur, silicon, germanium, and fluorine in order of increasing atomic radius, that is increasing size.
00:22
So it's going to go such that we have fluorine will be the smallest because fluorine, or the let me just put it, the way to do this is to look at the period number first.
00:37
So fluorine is in period number two and that is the smallest period number.
00:44
Then we are left with element in period number three, in which case we will be looking at calcium and we'll be looking at sulfur and we'll also be looking at silicon.
00:59
So we are looking at calcium, sulfur, and silicon.
01:05
So i'll just read this up.
01:06
So we have calcium, silicon, and sulfur.
01:13
But if we look at it, what happens to size across the period? size decreases across the period.
01:21
So we are going from, so if you look at a period, you have calcium, you will have silicon, and then you have sulfur...
