Why did John Dalton think that elements are made of single atoms?

The constant proportions - combining different substances into other substances always required the same proportions of each substances; in the case of gases, the numbers come in simple ratios. For example, 2 volume units of hydrogen + 1 volume unit of oxigen combine to form water.

∙ 11y agoIn his theory, John Dalton proposed the following:
Every element is made up of tiny, unique particles called atoms
that cannot be subdivided.
Atoms of the same element are exactly alike.
Atoms of different elements can join to form molecules.
An atom is the smallest part of an element that still has the
element's properties. Imagine dividing a coin made of pure copper
until the pieces were too small for you to see. if you were able to
continue dividing these pieces, you would be left with the simplest
units of the coin -- copper atoms. All the copper atoms would be
exactly alike. Each copper atom would have chemical properties
mostly the same as the coin you started with.

All substance are built from what?
All Substances are built from Atoms
What do you call someone who studies elements atoms and molecules?
you call it chemist i think
Who was the first scientist generally accredited with putting the study of chemistry on a firm experimental basis?
John Dalton because Dalton predicted new combinations of elements; these new combinations were found providing evidence that Dalton's theory worked.
What is a collection of atoms called?
A large collection of neutral atoms with the same atomic number is a sample of an element. Elements include include lithium, hydrogen, neon, and oxygen. Note that different isotopes of elements exist; these are atoms with the same atomic number but having a different number of neutrons.
What are the 2 most common elements and compounds?
the most common element is hydrogen and its molecule of two hydrogen atoms is the most common molecule
John Dalton believed that atom could join together form?
John Dalton proposed that elements are made of extremely small particles called atoms. He believed that atoms could join together or "hooked" to form elements.
Which best describes john Dalton's observations of elements in any given compound?
Dalton discovered that the atoms that combine to form compounds are distinguished from one another by their atomic weights. He also learned that all atoms of a given element are identical.
How did Dalton think atoms formed new substance?
he discovered it
What did John Dalton think about atoms?
A thing that had a centre with a outer rim
What elements exist as single atoms not bonded to other atoms?
The group of elements that exist as separate atoms are the noble gases. Radon, neon, xenon, argon, helium, and krypton are those elements.
The idea that matter is made up of fundamental particles called atoms?
Dalton proposed it in Dalton's atomic theory (i think)
Did Democritus describe that Atoms are small hard particles?
No, Democritus was the first to think of atoms, Dalton thought the atom was an indestructible sphere.
How did John Dalton arrive at his conclusions?
To develop his Atomic theory, John Dalton supported his claims on his own previous research on combination of gases, his findings regarding how certain gases could only be combined in certain proportions, no matter if they shared common elements, that led him to think that elements combination was being realized at a very primary level, among very tiny particles. He called those particles 'atoms', from the Greek word 'atomos', which means 'uncut'.
Who proposed each element is composed of extremely small particles called atoms?
i think Dalton said it
How were John Dalton's findings significant?
John Dalton held many roles within his lifetime. He was a chemist, meteorologists, and physicist. He affected the world through his development of the atomic theory and by providing feedback on his research conducted for color blindness.
All substance are built from what?
All Substances are built from Atoms
Who was John Dalton and what did he do and when did he do it?
John Dalton (1766 1844) was a British chemist and physicist, and is best known for his work on gasses and the atomic theory.Dalton's Law states that the total pressure of a gas mixture is equal to the sum of the partial pressures of all the constituent gasses..Dalton's contribution to the atomic theory served as the foundation for modern chemistry.Dalton's atomic theory suggested that:different elements have atoms of different weights, and that all atoms of a given element are identicalatoms form compounds in the same relative quantities, and their relative ratios are always integersatoms are indestructibleHe proposed the atomic theory, that atoms were like a huge mass of evenly distributed negative charges containing electrons whose positive charges were uniformly spread within.You can think of a big piece of cake with raisins stuck into it. Preferably then it has come to be known as the "plum pudding" modelJohn Dalton used evidence from his experiments with gases to show that there are many types of atoms, not just one kind. He came up with the concept of elements and compounds. He thought incorrectly that gas elements such as oxygen come as single atoms which can't be broken.His atomic theory has since been superseded.
