Make your own Periodic table

Folks,
These are exampes of past periodic tables. This is not an easy task as the treand must track from left to right and another trend from top to bottom. So, each item in a horizontal row must have something in common. Likewise, each item in a vertical column must have something in common.
For a C you can just have common features inthose two ways. However, for a B or higher you need to have a trend that increases as you move from left to right in a horizonal row and a different trend that increases as you move from top to bottom in a column.
So, follow the rules:
1. Must have at least 25 items
2. Must be a horizontal trend
3. Must have a vertical trend

There are no new items in chem this summer. I will post a new batch in August. Stay tuned!
