Answer the following question given this paragraph: Nonmetals tend to gain electrons in chemical reactions and have a high attraction for electrons within a compound. The most reactive nonmetals reside in the upper right portion of the periodic table. Since the noble gases are a special group because of their lack of reactivity, the element fluorine is the most reactive nonmetal. It is not found in nature as a free element. Fluorine gas reacts explosively with many other elements and compounds and is considered to be one of the most dangerous known substances. Q: What elements have the highest attraction for electrons? Choices: - gases - metals - carbons - nonmetals A:
**Answer**
nonmetals
