Ques:Q: When a metal is oxidized and a nonmetal is reduced in a redox reaction, what is the resulting compound called? Read this paragraph and choose the correct option from the provided answers: There are many other examples of redox reactions in which two neutral elements combine to make a compound. These often take the form of a metal being oxidized and a nonmetal being reduced, resulting in an ionic compound. Two nonmetallic elements can also undergo a redox reaction of this type, in which the less electronegative element is oxidized and the more electronegative element is reduced. Choices: - soluble compound - alloy - magnetic compound - ionic compound A:

Ans:ionic compound
