Who did not have experimental evidence to support his of the atom?
Democritus did not have experimental evidence to support his idea of the atom. Instead, his idea was based on philosophical reasoning and speculation.
Who was the Indian sage who first discovered the idea of atom?
manu
Who did not have experimental evidence to support there theory of a atom?
Ancient Greek philosophers such as Democritus and Leucippus did not have experimental evidence to support their theory of the atom. Their idea of the atom was purely philosophical and lacked experimental verification until much later.
Why has our idea of what the atom looks like changed so many times?
Our idea of the atom has changed over time as new experimental evidence and theoretical advances have been made. Early models were based on limited information and as technology improved, we discovered more about the structure of the atom. Each new model built upon the shortcomings of the previous one, leading to our current understanding based on quantum mechanics.
Who was th first scientist to give evidence to support democritus idea about atom?
dylan narvadez
Is the fact that the atom was discovered significant to the agruement that matter is made of atoms?
Yes, the discovery of the atom was significant in supporting the argument that matter is made of atoms. The concept of the atom provided a theoretical foundation to understand the building blocks of matter and how they interact. Additionally, subsequent experimental evidence and advancements in atomic theory further solidified the idea that matter is indeed composed of atoms.
How has the idea of the atom developed and changed over time?
At first we didn't now that the atom existed. It was Einstein who discovered that pollen grains were moving in a glass of water. Why? It was because as he later confirmed that the water particles were pushing it in an unbalanced way. Other scientists later discovered that there are protons, neutrons and electrons in an atom.
How did Thomson's discovery change Dalton's atomic theory?
Thomson discovered that atoms can be cut. He found this out while studying rays traveling between charged metal plates in a vacuum tube. He discovered that the rays were consisted of negatively charged particles. He had just discovered electrons. He discovered all of this on a trip from America. Since electrons are so small, he believed that they could only be from inside of the atom. Since Thomson's discovery of the electron, John Dalton's theory that atoms are indivisible had to be changed.
What is the name of the Chinese explorer who discovered America?
Some archaeologists have theorized a voyage from China to the Americas in ancient times, but there is little physical evidence to confirm the idea.
Who first came up with the idea that the atom is mostly empty space?
The idea that the atom is mostly empty space was first proposed by Ernest Rutherford based on his gold foil experiment in 1909. This experiment led to the discovery that most of an atom's mass is concentrated in a nucleus at the center, surrounded by electrons in vast empty space.
Who discovered that electrons were found in the electron cloud?
i have no idea when it was discovered
Which is a big idea and for matter and change?
Which is a "big idea" for matter and change? The universe is very old and very large. Forces cause changes in motion. The laws of nature have all been discovered. Atoms are the building blocks of all things.
