Answer:
D. Water is the most abundant atom in Earth’s atmosphere.
Explanation:
An atom can be defined as the smallest particle of an element (e.g., oxygen, hydrogen, etc). Water is a molecule (H2O) because its atoms are connected by molecular bonds (i.e., water is not an atom). Water is the most abundant molecule on the Earth's surface which covers more than 70 percent of the world's surface. A water molecule contains one oxygen (O) and two hydrogen (H2) atoms which are connected by covalent bonds. Water is also a compound known as a diatomic molecule, i.e., a molecule composed of two atoms of the same type.
