What else can I help you with?
Which of Jhon Daltons statements about the atom was proven false because of the discovery of isotopes?
Dalton said that all atoms of one element are identical. they are chemically identical but not identical in mass. he did not know of isotopes, which are chemically identical atoms with different numbers of neutral neutrons. ex: all carbon atoms act the same chemically but some mass at 12, others at 14.
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 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.
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 scientist said atoms are spheres?
James Clerk Maxwell, a Scottish physicist, suggested that atoms were tiny spheres in the 19th century. His work built on the atomic theory proposed by John Dalton.
When is an element said to be chemically reactive?
An element is said to be chemically reactive when it combines with another element. These two elements will create a new compound.
He said that compounds are formed when atoms of different elements combine?
Yes, compounds are formed when atoms of different elements chemically bond together. This bonding involves the sharing or transfer of electrons between the different atoms to achieve a more stable configuration. The resulting compound often exhibits different physical and chemical properties compared to its constituent elements.
Which scientist said atoms constantly move?
The Greek philosopher Democritus was the first to propose that matter is made up of atoms that constantly move. This was further collaborated by the Scottish botanist Robert Brown, who formulated the famous Brownian Motion.
Who said this atoms of differnet elements are differnet?
who said this atoms of different elements are different
Who was the English scientist that said all matter is made up of a relatively small number indivisible particles called atom?
The English scientist who proposed that all matter is made up of indivisible particles called atoms was John Dalton. He introduced his atomic theory in the early 19th century, which laid the foundation for modern chemistry.
Who said that atoms constantly move?
Democritus was the one who said that atoms constantly move. He was a Greek philosopher and said this around 440 BC.
