A. They will form new substance
Explains:
Atoms of different elements can combine to make new substances. A molecule is formed when two or more atoms join together chemically. If atoms combine that are of two or more different elements, we call that a compound. All compounds are molecules, but not all molecules are compounds. When two hydrogen atoms combine with one oxygen atom, it becomes the compound water. The oxygen we breathe is actually two atoms of oxygen combined, so it is a molecule of oxygen. We use abbreviations for elements. These abbreviations for elements are called chemical symbols. When two or more atoms combine to form a molecule or compound, the abbreviation is known as a chemical formula. The chemical formula for an oxygen molecule is O2.
