The first suggestion that matter consists of atoms is attributed to the ancient Greek philosopher Democritus, around the 5th century BCE. He proposed that everything in the universe is made up of indivisible units called "atomos," meaning "uncuttable." This concept laid the groundwork for later atomic theory, although it wasn't scientifically validated until much later, with developments in chemistry in the 19th century.

Who was the first person to state that matter is made up of atoms?
The idea that matter is made up of atoms was proposed by the ancient Greek philosopher Democritus around 400 BCE. He believed that all matter consists of tiny, indivisible particles called atoms.
One of the first people to state that matter is made up of atoms was?
The first person to state that matter is made up of atoms was the ancient Greek philosopher Democritus in the 5th century BC. He proposed that all matter is composed of indivisible particles called atoms.
What did scientist understand first about the atom?

Which part of modern atomic theory was first developed by john Dalton?
John Dalton's development of modern atomic theory primarily introduced the concept that matter is composed of indivisible particles called atoms. He proposed that each element consists of unique atoms with specific weights and that chemical reactions involve the rearrangement of these atoms. Dalton's theory laid the groundwork for understanding chemical combinations and the conservation of mass in reactions.
What was john daltons four postulates of the tomic heory?
John Dalton's atomic theory consists of four key postulates: First, all matter is made up of indivisible particles called atoms. Second, atoms of the same element are identical in mass and properties, while atoms of different elements differ. Third, atoms combine in simple whole-number ratios to form compounds. Finally, during a chemical reaction, atoms are rearranged but not created or destroyed, maintaining their identity throughout the process.

Describe the discovery that demonstrate for the first time that atoms are not the smallest particles of matter?
The discovery of the subatomic particles demonstrated for the first time that atoms are not the smallest particles of matter. Electron was the first subatomic particle discovered by J.J. Thomson.
What is matter made from?
Several answers. First is atoms, all matter is composed of atoms. But then you can worry about atoms. Best (current) answer is quarks, but if you like string theory them maybe all matter is just "frozen" energy. That would certainly help explain e=mc2.
What would be the formula for an alkyne with 3 carbon atoms?
The formula for an alkyne with 3 carbon atoms is C3H4. It consists of three carbon atoms and four hydrogen atoms, with a triple bond between the first and second carbon atoms.

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.
How many atoms in 2KClO3?
To determine the number of atoms in 2KClO3, we first need to break down the compound into its constituent elements. KClO3 consists of 2 potassium (K) atoms, 2 chlorine (Cl) atoms, and 6 oxygen (O) atoms. Therefore, in 2KClO3, there are a total of 4 potassium atoms, 4 chlorine atoms, and 12 oxygen atoms.
Who was the first to suggest that matter is made of small particles called atoms?
Peter Waltan......hope that helps!

What was the first said by scientists about atoms?
Early scientists speculated that the concept of atoms could explain the behavior of matter. The idea of atoms was proposed by ancient Greek philosophers such as Democritus around 400 BC, suggesting that matter is composed of indivisible particles. It wasn't until modern times that scientists were able to provide experimental evidence for the existence of atoms.
