answer input:
spelling counts but capitalization doesn’t

Explanation:

A chemical compound is defined as a substance made up of at least two different elements that are chemically bonded together. Marble (e.g., calcium carbonate, \(CaCO_3\)) consists of calcium, carbon, and oxygen elements. Water (\(H_2O\)) consists of hydrogen and oxygen elements. So the blank should be filled with "elements" as compounds are formed from the chemical combination of elements.

Answer:

elements
