- Title : Atomic structure and Theory, about Daltan Principle and Rutherford
In this video I explained about what is atom and who introduce the atoms
About their principle
John Dalton's Atomic Theory, also known as the Dalton Principles, revolutionized chemistry and our understanding of matter. Here are the key postulates:
Dalton's Postulates (1803)
1. *Matter is composed of tiny particles called atoms*: Atoms are indivisible, smallest units of matter.
2. *Atoms of the same element are identical*: Atoms of the same element have the same properties, mass, and size.
3. *Atoms of different elements differ*: Atoms of different elements have distinct properties, masses, and sizes.
4. *Atoms combine in simple whole-number ratios*: Atoms of different elements combine in fixed, simple ratios to form compounds.
5. *Atoms cannot be created or destroyed*: Atoms are indestructible and conserve their identity in chemical reactions.
Key Implications:
1. Atomic weight concept
2. Law of Multiple Proportions
3. Law of Definite Proportions
4. Foundation for modern chemistry and physics
Limitations:
1. Didn't account for subatomic particles (electrons, protons, neutrons)
2. Assumed atoms were indivisible
Influence on Science:
1. Development of modern atomic theory
2. Discovery of subatomic particles
3. Understanding of chemical bonding type in comment box
