Where are the most reactive nonmetals located on the periodic table?

• A. Lower left corner
• B. Lower right corner
• C. Middle of the periodic table
• D. Upper right corner, excluding noble gases

Answer: (D)

Verified step by step guidance

1. Understand that reactivity in nonmetals is related to their tendency to gain electrons to achieve a full valence shell.
2. Recall that nonmetals are generally found on the right side of the periodic table, and their reactivity increases as you move up a group because atoms are smaller and attract electrons more strongly.
3. Recognize that the most reactive nonmetals are located in the upper right corner of the periodic table, specifically in groups like the halogens (Group 17), which are one electron short of a full valence shell.
4. Note that noble gases (Group 18) are excluded because they have full valence shells and are generally unreactive.
5. Conclude that the most reactive nonmetals are found in the upper right corner of the periodic table, excluding the noble gases.
