The Modern Atomic Theory by Chance LeStourgeon https://padlet.com/chance3055/8s93tsp98mbv By. Chance, Jorge, Kiersten, Kendall, Maddie, and Elizabeth. In chemistry and physics, atomic theory is a scientific theory of the nature of matter, which states that matter is composed of discrete units called atoms. It began as a philosophical concept in ancient Greece and entered the scientific mainstream in the early 19th century when discoveries in the field of chemistry showed that matter did indeed behave as if it were made up of atoms. en-us 2014-09-10 02:00:41 UTC 2025-04-24 10:18:36 UTC hello@padlet.com http://d262le4z25sx36.cloudfront.net/portraits/announcement.jpg Question 1: Who or What is your model named for? chance3055 https://padlet.com/chance3055/8s93tsp98mbv/wish/33538332 Named by Louis de Brogile

But The actual theory was created by a scientist named John Dalton, Brogile perfected the method.

"Erwin Schrödinger, fascinated by this idea, explored whether or not the movement of an electron in an atom could be better explained as a wave rather than as a particle."

This marked the first truly scientific theory of the atom, since Dalton reached his conclusions by experimentation and examination of the results in an empirical fashion
