I think the periodic table is a red herring.
If you look at the first letters you have A A A S A A ... so I would think the next two letters are A S
For the second letters you have c l m b rs. You have a c, and a b, going down, so I would think the next letter would be a.
Then you have lm and rs (sequential pairs). 6 letters apart (l to r and m to s ). So if you follow this pattern next pair will be xy.
So it looks like the next two second letters would be a x y
So that the next two are Aa and Sx.

Sorry I meant next 3 second letters are a x y. I looked at the periodic table and there is no pattern I can see in the positions of the elements given.08/26/20
