For this question, we'll use the periodic table to help us from the chemical symbols find the name of the element.
00:08
The first chemical symbol is p.
00:10
If you look at the periodic table and we find p in group 15, so the 15th column to the right, third row down, p is phosphorus.
00:25
And then the next one is chemical symbol s.
00:28
It turns out s is right next to p, which is phosphorus, and s is sulfur.
00:37
The next one is kr.
00:39
Kr is found close to sulfur.
00:41
Go a little bit farther right to the last column of the periodic table, about halfway down.
00:47
Kr is krypton.
00:49
The next one is f .e.

F .e is found in the fourth row, which is the first row of the transition metals, right in the middle...
