How can you move across and down the periodic table?

Question

I have to do this game board project and my board is going to be the periodic table. Each element is a different space. I need ideas for how to move up spaces on the note cards. For example, one might be your atomic mass increased, move up 2 elements.

Answer 1

Alpha decay - move back two elements.
Beta-plus decay - move backards one element
Beta-minus decay - move forward one element

Answer 2

Another might be: your electronegativity increased, move up and to the right.
