For this question, you are given a periodic table that looks something like this with shaded boxes.
00:10
It doesn't tell you, but this one's sodium.
00:14
This one's barium.
00:17
Carbon, oxygen, chlorine, and argon.
00:23
The first question asks four elements that are non -metals.
00:28
The non -metals are going to be in the upper right hand corner, so we're looking at carbon, oxygen, chlorine, and argon.
00:35
The next asks for two elements.
00:36
Elements that are metals.
00:39
That's going to be the two on the left hand side, sodium and barium.
00:45
Then it asks for three elements that are gases at room temperature.
00:49
The ones that are gases at room temperature are oxygen, chlorine, and the noble gas, argon.
00:56
D asks for three elements that are solid at room temperature.
01:00
That would be the other three, sodium, barium, and carbon.
01:04
E then asks, one pair of elements likely to form a covalent compound.
01:18
The elements that come together to form covalent compounds are the ones that are non -metals.
01:25
So we could have carbon and oxygen come together to form a covalent compound, or really any of these non -metals coming together except for the noble gas, because the noble gas won't form covalent compounds.

The next one is f...
