What constitutes a compound?

A chemical combo of two or more molecules
A mixture of two elements
A chemical combo of two or more atoms of different elements
A physical blend of two atoms

The correct answer is: A chemical combo of two or more atoms of different elements

A compound is a type of chemical combination between two or more different elements. This makes option C the correct choice, since it includes both the components of "chemical combo" and "different elements". Option A is incorrect because it does not specify different elements and could also refer to a single molecule. Option B is incorrect because it only mentions two elements without specifying a chemical combination. Option D is incorrect because it refers to a physical blend rather than a chemical combination.
