i have to create a periodic table that is based on ANY topic(all appropriate). items in the verticle columns must be similar in some manner and have some gradual change as you move down the family. there should be a pattern, or trend, in the change of charcteristics as you move across a row/period. so the entire project is basically an organized chart that consists of specific patterns or trends, based on a particular subject.

G, H, and I (ramdom variables) belong to a family of very active metals, all of which react with chlorine to produce salts with the general form XCl. G is a member of the first period to contain 18 elements. H has the highest ionization energy of the group and I has the lowest. What are the elements representing G, H, and I?

In a combustion reaction, by the way.

And, this is the formula:

2 C5H12O (l) + 15 O2 (g) → 10 CO2 (g) + 12 H2O (g)

Thanks in advance!

You know how the last problem's the hardest? Well, this is mine:

_ CH3COOH + _ O2 --> ?

It's a single replacement problem I think. Idk how to do it, the teacher didn't say anything about combining 3 compounds/polyatomic ions in this type of thing.
