pls answer this question ​

Answer 1

Answer:

A molecule is formed when two or more atoms join together chemically. ... 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.
