Atoms are the building blocks of everything you see around: the screen you are looking at, your study table, your books, etc. Such is the amazing power of nature and fundamental nature of these particles. Despite the discovery of sub-particles like electrons, protons and neutrons, an atom continues to remain the fundamental particle because of the fact that it is the smallest unit humans can calculate and model that exhibits the chemical properties of an element.

an atom is the smallest constituent particle of an element which exhibits the chemical properties of an element and also can take part in a chemical reaction. Atoms are extremely small and their sizes are about an angstrom. \big(1(1 angstrom (\text{A}^{\circ})= 10^{-10}\text{ m}.\big)(A

 m.) Although visualizations are nowadays made by very sophisticated microscopes, no one has actually seen an atom. Initial studies showed that it is spherical in shape.

Compounds are made of two or more atoms of different elements, such as water (H2O) and methane (CH4). ... Molecules of compounds have atoms of two or more different elements. For example, water (H2O) has three atoms, two hydrogen (H) atoms and one oxygen (O) atom.

Answer:

atoms = An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across. They are so small that accurately predicting their behavior using classical physics—as if they were tennis balls, for example—is not possible due to quantum effects.

Explanation:

molecules =smallest unit into which a substance can be divided without changing its chemical nature
