Chemically, water is composed of how many atoms of hydrogen and how many atoms of oxygen?

Water, in its chemical structure, is represented by the formula H₂O. This indicates that each water molecule consists of two atoms of hydrogen and one atom of oxygen. The hydrogen atoms bond with the oxygen atom to form the stable molecule that is essential for life. Understanding this composition is fundamental because it highlights the unique properties of water that are vital for various chemical reactions and biological functions.

The incorrect options reflect misunderstandings of the molecular formula. For example, having one hydrogen and two oxygens or three hydrogens would not accurately represent a water molecule, as those combinations do not occur naturally and do not exhibit the properties of water. Responding to this question requires recognizing the correct atomic ratios that define pure water.
