Study Notes

Ancient Greek Ideas on the Atom

Democritus of Abdera lived from 460 to 370 B.C. and is often referred to as one of the early atomic theorists.
Leucippus of Miletus, who lived around 500 B.C., is recognized as Democritus' mentor and co-founder of atomic theory.
Both scholars proposed that matter can be repeatedly divided into smaller pieces.
They introduced the concept of "atomos," meaning indivisible, signifying the smallest possible unit of matter that cannot be divided further.
Their ideas laid foundational principles for future scientific understanding of atomic structure.

Atomic Theory Overview

Matter consists of tiny, indivisible particles known as atoms; the term "atom" originates from the Greek word atomos, meaning "uncuttable."
Atoms are characterized as indestructible, impenetrable, and unchangeable entities.

Behavior and Composition of Atoms

Atoms are in perpetual motion within a "void", continuously interacting in ways that either repel upon collision or combine into clusters.
Their solidity indicates that there is no internal empty space, which contributes to their stability against disintegration or destruction.

Structure of Atoms

Atoms exhibit a homogeneous nature; they lack internal structures such as subatomic particles, emphasizing their simplistic design.
They exist in a variety of shapes and sizes, indicating diversity in atomic composition across different elements.
