What scientist said that matter can not be divided into smaller pieces?
Democritus in 400BC came up with the theory of the atom. His theories were not excepted until the 17th century. John Dalton then explained the atomic theory of matter: 1. All elements are made of atoms. 2. All atoms of the same element are identical, but differ from any atoms of a different element. 3. Atoms cannot be created or destroyed. 4. Atoms of different elements combine in simple whole number ratios. 5. Atoms can be combined, separated, or rearranged.
What is the modification of John Dalton's atomic theory?
Daltons said All elements are made up of atomsAtomos are indivisible and indistructableAtoms of a given element are identical in mass and in all other propertiesA compound is formed when the atoms of two or more elements combine
Which scientist said an orbital must have opposite spins?
I believe no scientist said exactly this. It is the (two) electrons in the same orbital that must have opposite spins. And the scientist who said that was Wolfgang Pauli in 1925. (Pauli exclusion principle)

The Greek philosophers Leucippus and Democritus first theorized about atoms. In fact, that's who named them atoms.
What scientist that said that atoms can be changed chemically?
Dalton
Which scientist said that different elements are made of different types of atoms?
Thomson
Who said matter was composed of atoms?
Robert Boyle
Who said matter was made of particles called atoms?
Democritus did. The modern version of the atomic theory is based on the research of Dalton.
What did Democritus believe the universe is made of?
Democritus believed that matter is made of tiny indivisible particles called atoms. He believed that the atoms have always been, and always will be, in motion; that there are an infinite number of atoms, and kinds of atoms, which differ in shape, and size.
How do scientists define matter?
Matter must have mass and volume, and occupy space. There are things like light and sound that are said to have no matter.
Who said that atoms are made or a single material?
bohr said this
Who said that everything is made out of atom?
