Where are the most reactive metals located?
a) upper left of the periodic table
b) lower left of the periodic table
c) upper right of the periodic table
d) lower right of the periodic table

option B = lower left of the periodic table

Explanation:

The most reactive metals are located at the bottom left corner of periodic table. These metals are reactive in the sense that they can react with water very easily.

Examples include lithium, sodium potassium. As we move down the group in this column metallic character increase. Their atomic radius also increases and electron can easily donated. which means metals became more reactive.

These metals can also react very easily with O2 in atmosphere that's way these are stored in inert atmosphere. The most reactive metal in periodic table is francium.

The answer to this question is B on Edgenuity!
