Solution: Which region of the periodic table shown here contains elements that are easiest to oxidize?

Problem

Which region of the periodic table shown here contains elements that are easiest to oxidize? The periodic table is labeled with four regions: a) the two left-most columns; b) the middle rows; c) the section on the right along a diagonal from upper left to lower right; and d) the section to the right of section c.

Solution

Recall the mnemonics LEO the lion goes GER:

Loss Electron Oxidation

Gain Electron Reduction

Let's determine the group for each region specified in the periodic table:

• Region A → Group 1A and Group 2A (s-block elements)

• Region B → d-block elements

• Region C → p-block elements

• Region D → Group 7A and Group 8A
