Who is the scientist who proved that atoms exist?
John Dalton is considered the scientist who developed the modern atomic theory, providing evidence for the existence of atoms through his experimentation with gases.
What scientist discovered that atoms have a positive charge?
Ernest Rutherford is the scientist who discovered that atoms have a positive charge. Through his gold foil experiment, he found that atoms have a small, positively charged nucleus at their center, surrounded by negatively charged electrons.
What is the name of he scientist that discovered that atoms have positive charges?
Ernest Rutherford was the scientist who discovered that atoms have positive charges through his gold foil experiment, which led to the development of the nuclear model of the atom.
What nineteenth-century English scientist offered proof that atoms existed?
John Dalton, a British scientist, offered proof of the existence of atoms in the nineteenth century through his atomic theory. Dalton's theory proposed that elements are made up of atoms that are identical in mass and properties, and that compounds are formed through the combination of these atoms in simple whole-number ratios.
Who was the first scientist to question the idea that atom were uncutable?
The first scientist to question the idea that atoms were indivisible was John Dalton, an English chemist, in the early 19th century. Dalton proposed that atoms were not actually indivisible, as previously believed, but rather could be rearranged in chemical reactions.
What scientist that said that atoms can be changed chemically?
Dalton
What scientist said matter is made of atoms?
The scientist who first proposed that matter is made of atoms was John Dalton, in the early 19th century. Dalton developed atomic theory to explain chemical reactions and the behavior of gases.
What scientist worked with gases in 1808 and published theory that were hard spheres?
It was dalton
What scientist said all matter is made of atoms?
The scientist who proposed that all matter is made of atoms was John Dalton in the early 19th century. His atomic theory revolutionized the field of chemistry and laid the foundation for modern atomic and molecular theory.
Red spheres represent oxygen atoms and green spheres represent chlorine atoms. Write a balanced chemical equation for the reaction?
This is the picture.
Who worked with gases in 1808 and published theory that atoms were hard spheres?
John Dalton is credited with proposing the theory that atoms were hard spheres based on his work with gases in 1808.
What scientist said all matter is made up of atoms?
The scientist who proposed that all matter is made up of atoms was John Dalton, known for his atomic theory in the early 19th century. Dalton's theory stated that all elements are made up of tiny indivisible particles called atoms.
Which scientist said that atoms are the smallest particle of an element that retains its chemical properties?
John Dalton, an English scientist, proposed the theory that atoms are the smallest particle of an element that retains its chemical properties. His work on atomic theory laid the foundation for modern chemistry.
What is the name of the scientist who discovered that atoms have positive charged?
Ernest Rutherford is the name of the scientist who discovered that atoms have positively charged nuclei.
What did democritus create?
well, according to my knowledge, he didn't really "create" anything in fact he found out that everything is made of atoms but he described atoms as being solid spheres. But many people disagree with his theory. Modern Chemistry would have not been the same without the contribution of our future scientist Democritus the man who developed atomism.
