E decreases from right to left.
E decreases from top to bottom.
E decreases from bottom to top.

These are the multiple choice answers

Answer 2

down a GROUP (top to bottom), electrons in outer shell experience less attraction as they are more effectively shielded -> greater ease of removal -> lower E

Answer 3

Thanks man!
