Answer:

I'm not sure what is unclear but I can try to help...

Explanation:

So the group is the number at the top and is verticle. So H,Li,Na, and K share the same Group, 1.

The period is the number at the side and is horizontal. Soo H and He are Period 1.

Now using this information we can find the specifics of each element.

Chlorine, for example, is Group 17A and Period 3 because it matches those.

Let me know if you need further explanation :)
