Scientists that Contributed to the development of Atomic Structure

Scientists that Contributed to Atomic Structure ‎ Democritus (400 BC) ‎ Democritus (460 – c. 370 BC) was an Ancient Greek pre-Socratic philosopher from Abdera, primarily remembered today for his formulation of an atomic theory of the universe. Democritus wrote extensively on a wide variety of topics. None of Democritus’ original work has survived, except through second-hand references. Many of these references come from Aristotle, who viewed […]

Atomic Theories

Ancient Greek  Ancient Greek atomic theory, pioneered by Leucippus and Democritus in the 5th century BC, proposed that all matter is composed of indivisible particles called atoms. These atoms were thought to be eternal, unchangeable, and in constant motion within empty space. While this theory was a significant early contribution. The core idea:  Leucippus and Democritus believed that all […]

What is an Atom?

Atoms are the basic particles of the chemical elements and the fundamental building blocks of matter. An atom consists of a nucleus of protons and generally neutrons, surrounded by an electromagnetically bound swarm of electrons. The chemical elements are distinguished from each other by the number of protons that are in their atoms. For example, any atom that contains 11 protons is sodium, and any atom […]

Atomic Models

Atomic Models Solid Sphere Model The solid sphere model, also known as Dalton’s atomic theory, was the first atomic model proposed by John Dalton in 1803. It posits that all matter is composed of tiny, indivisible particles called atoms, which are solid, indestructible spheres. Different elements are made of atoms with different masses and properties, and […]

What is an Atomic Structure?

Atoms are the smallest component of matter and are indivisible. They are the building blocks for the matter. “Atom” is derived from the Greek word, ‘A-tomio’, meaning uncuttable or indivisible. In the initial days, all ideas regarding the matter were merely theoretical, they could not be carried out experimentally. John Dalton, a British school teacher, […]
