Which category of elements on the periodic table typically forms negative ions (anions)?

• A. Transition metals
• B. Nonmetals
• C. Noble gases
• D. Alkali metals

Answer: (B)

Verified step by step guidance

1. Understand that ions are atoms or molecules that have gained or lost electrons, resulting in a net charge.
2. Recall that elements tend to form ions to achieve a stable electron configuration, often resembling the nearest noble gas configuration.
3. Recognize that metals typically lose electrons to form positive ions (cations), while nonmetals tend to gain electrons to form negative ions (anions).
4. Identify that transition metals and alkali metals generally form positive ions, and noble gases are mostly inert and do not form ions under normal conditions.
5. Conclude that nonmetals are the category of elements on the periodic table that typically form negative ions (anions) by gaining electrons.
