Answer:
C.) Middle
Explanation:
A.) is incorrect because elements on the bottom of the periodic table can be metals, nonmetals, or metalloids. However, the majority of these elements would be metals.
B.) is incorrect because elements on the right side (aka. the p-block) of the periodic table are mostly nonmetals. This excluding the stair case elements which are metalloids and elements to the left of the stair case which are metals.
C.) is correct because elements located in the middle of the periodic table (aka. the d-block) are always metals. The elements in this section are usually nicknamed the "transition metals". It should be noted that elements on the left side (aka. the s-block) of the periodic table are also metals (excluding hydrogen).
