Hi there.
00:03
In this question, we have an indicated element.
00:06
It's indicated by the box being shaded.
00:09
And we see that it is in period three.
00:14
All right.
00:15
As we look over to where it's located there on the right side, we see that it is in the p block.
00:24
The p block means those six groups to the right side of the periodic table where they fill in or the last electron is entering p1 through p6, corresponding to each of these.
00:38
Well, this one is in the third group in the p block.
00:47
So if it's the third group in the p block, that means it's going to be ending its last electron is going to go into p3.
00:56
Therefore, that means we need to complete our electron configuration until we get to 3p3.
01:03
And then it will be done.
01:05
So let's go ahead and start.
01:07
We always start with 1s...
