An atom is the smallest constituent unit of ordinary matter that constitutes 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 billiard balls, for example – is not possible due to quantum effects. Current atomic models use quantum principles to better explain and predict this behavior.

Atoms are defined as “the basic building blocks of matter”. It is the smallest constituent unit of matter that posses the properties of the chemical element. Atoms don’t exist independently, instead, they form ions and molecules which further combine in large numbers to form matter that we see, feel and touch. Atoms are much too small to be seen; hence experiments to find out their structure and behavior have to be conducted with large numbers of them. From the results of these experiments we may attempt to construct a hypothetical model of an atom that behaves like the true atom.

Atoms is the smallest components of an element, characterized by a sharing of the chemical properties of the elements and a nucleus with neutrons protons and electrons.
