Interpretation: The symbol of nonmetal in the formula
Concept Introduction: Every matter is made of chemicals; the importance of chemistry is that it's the study of everything. Chemistry is all about how something interacts to affect the structure, composition, as well as knowing properties of substances.

Answer to Problem 8STP
Correct answer: The correct is option (D).
Explanation of Solution
Reason for correct option:
The noble gases don’t react with anything. They are neither metalloid nor a metal. Noble gases are also called ‘inert gas’. They are colorless and odorless.
Neon is a noble gas. The
