Final answer:
The elements with atomic numbers 11 through 17 change classifications from metal to metalloid to nonmetal as their atomic number increases.
Explanation:
The elements with atomic numbers 11 through 17 are Sodium (11), Magnesium (12), Aluminum (13), Silicon (14), Phosphorous (15), Sulfur (16), and Chlorine (17).
If we look carefully at the periodic table, we will find that Sodium, Magnesium, and Aluminum are classified as metals. Silicon is considered a metalloid, which means it has properties of both metals and nonmetals. Phosphorous, Sulfur, and Chlorine are nonmetals. So, as atomic numbers increase from 11 through 17, the classification of the elements changes from metal to metalloid to nonmetal.
