LOS MODELOS ATOMICOS DE 1800 History Timeline and Biographies

John Dalton's Atomic Theory

In 1803, John Dalton proposed his atomic theory, which stated that all matter is made up of indivisible atoms. Dalton's model introduced the idea that atoms of different elements have different weights and combine in specific ratios to form compounds, laying the foundation for LOS MODELOS ATOMICOS DE 1800.

Dalton's Law of Partial Pressures

In 1805, Dalton further developed his theories by formulating the Law of Partial Pressures. This law explained how gases behave in mixtures, supporting the concept that atoms are the fundamental units of matter, consistent with LOS MODELOS ATOMICOS DE 1800.

Avogadro's Hypothesis

In 1811, Amedeo Avogadro introduced his hypothesis, which stated that equal volumes of gases, at the same temperature and pressure, contain an equal number of molecules. This concept was crucial in understanding molecular structure and supported the ideas in LOS MODELOS ATOMICOS DE 1800.

Dulong and Petit Law

In 1820, Pierre Dulong and Alexis Petit proposed a law regarding the molar heat capacities of elements, which reinforced the atomic theory by providing a method to determine atomic weights, further contributing to LOS MODELOS ATOMICOS DE 1800.

Michael Faraday's Electrolysis Evidence

In 1832, Michael Faraday conducted experiments on electrolysis, providing evidence for the existence of atoms and their role in chemical reactions, which aligned with the principles of LOS MODELOS ATOMICOS DE 1800.

Dmitri Mendeleev and the Periodic Table

In 1869, Dmitri Mendeleev created the Periodic Table of Elements, organizing elements based on atomic weight and properties. This development was a significant advancement in LOS MODELOS ATOMICOS DE 1800, as it provided a systematic way to understand atomic behavior.

Mendeleev's Predictions

In 1871, Mendeleev made predictions about the properties of undiscovered elements based on his periodic table, demonstrating the predictive power of atomic theory and reinforcing the ideas of LOS MODELOS ATOMICOS DE 1800.

Discovery of the Electron by J.J. Thomson

In 1897, J.J. Thomson discovered the electron, a subatomic particle, which challenged existing atomic models and led to the development of new theories, marking a pivotal moment in LOS MODELOS ATOMICOS DE 1800.

Max Planck and Quantum Theory

In 1900, Max Planck introduced quantum theory, which revolutionized the understanding of atomic and subatomic processes, contributing to the evolution of LOS MODELOS ATOMICOS DE 1800 into the 20th century.

Einstein's Theory of Brownian Motion

In 1905, Albert Einstein published his work on Brownian motion, providing empirical evidence for the existence of atoms and molecules, thus reinforcing the concepts established in LOS MODELOS ATOMICOS DE 1800.

Ernest Rutherford's Nuclear Model

In 1911, Ernest Rutherford proposed the nuclear model of the atom, which depicted a small, dense nucleus surrounded by orbiting electrons. This model marked a significant advancement from earlier atomic theories and was a key development in LOS MODELOS ATOMICOS DE 1800.

Niels Bohr's Model of the Atom

In 1913, Niels Bohr introduced his model of the atom, which incorporated quantum theory to explain electron orbits around the nucleus. Bohr's model represented a major leap forward from LOS MODELOS ATOMICOS DE 1800, integrating new scientific principles.

Quantum Mechanical Model by Schrödinger

In 1926, Erwin Schrödinger developed the quantum mechanical model of the atom, which described electrons in terms of probabilities rather than fixed orbits, further advancing the understanding of atomic structure beyond LOS MODELOS ATOMICOS DE 1800.

Discovery of the Neutron by James Chadwick

In 1932, James Chadwick discovered the neutron, completing the picture of atomic structure and leading to the modern understanding of atomic theory, a culmination of ideas that began with LOS MODELOS ATOMICOS DE 1800.
