## What is the development of the atomic theory?

The atomic theory, which holds that matter is composed of tiny, indivisible particles in constant motion, was proposed in the 5th cent. BC by the Greek philosophers Leucippus and Democritus and was adopted by the Roman Lucretius. However, Aristotle did not accept the theory, and it was ignored for many centuries.

## Who developed atomic theory?

chemist John Dalton

The modern atomic theory, which has undergone continuous refinement, began to flourish at the beginning of the 19th century with the work of the English chemist John Dalton.

**What is the definition of atomic theory in chemistry?**

Definition of atomic theory 1 : a theory of the nature of matter: all material substances are composed of minute particles or atoms of a comparatively small number of kinds and all the atoms of the same kind are uniform in size, weight, and other properties.

**What is the theory of atoms answer?**

Summary. Dalton’s atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that all matter is made of atoms, which are indivisible.

### What are the importance of atomic theory in the field of chemistry?

Atomic theory established that all matter is made of tiny particles, a discovery that led to amazing scientific breakthroughs in areas from modern chemistry to nuclear energy.

### What is the importance of atomic theory in the field of chemistry?

**Why is it significant for us to understand atoms and the development of the atomic structure?**

By learning about atomic structure, we can find out how atoms combine and form many compunds. By learning about atomic structure, we can find out how atoms collide. By learning about atomic structure, we can find out why atoms do not have mass. By learning about atomic structure, we can find out how atoms disappear.

**What is the importance of the development of atomic theories and structure to the modern concept of the atom?**

Atoms are the ultimate building blocks of all matter. The modern atomic theory establishes the concepts of atoms and how they compose matter. Atoms consist of negatively charged electrons around a central nucleus composed of more massive positively charged protons and electrically neutral neutrons.

#### What is the importance of the development of atomic models to the modern world?

Atomic models are important because, they help us visualize the interior of atoms and molecules, and thereby predicting properties of matter.
