Question

Using the periodic table, choose the more reactive non-metal.
S or As

Answer 1

Sulfur

Step-by-step explanation:

In general, elements are more reactive the more electronegative they are. The most electronegative elements are at the top-right of the periodic table. Since sulfur (S) is one unit up and one unit to the right of arsenic (As), it is considered more electronegative, and therefore more reactive, than arsenic.
