Democratis was a greek philosopher who lived about 2500 years ago. He decied to think that everyting is made up of small things that can not be divided and he called them atomos which means uncut. He thought the atoms in liquids were round and smoothe but the atoms in solids were rough and prickley. He did nothing to prove this and later Aristotle decided falsely that there was no limit to how many times something can be divided (also with no evidence).

What theory describes the way atoms are arranged within a molecule?
The theory that describes the way atoms are arranged within a molecule is called valence bond theory. This theory explains how covalent bonds are formed by the sharing of electron pairs between atoms and how the arrangement of atoms in a molecule is determined by the overlap of atomic orbitals.
When Dalton's theory is it possible to convert atoms of the one element into atoms of another?
No, according to Dalton's theory, atoms of one element cannot be converted into atoms of another. Atoms are indivisible and cannot be created or destroyed in a chemical reaction. This concept is known as the conservation of matter.
Is CCl4 to CH4 possible according to Dalton's theory?
According to Dalton's theory, chemical reactions involve the rearrangement of atoms and do not create or destroy atoms. Therefore, the transformation of CCl4 to CH4 would not be possible as it involves the addition of hydrogen atoms and the removal of chlorine atoms, which violates the law of conservation of atoms.
Is Dalton's atomic theory the same as the particle theory?
No b/c Thomson discovered that atoms can be cut. He found this out while studying rays traveling between charged metal plates in a vacuum tube. He discovered that the rays were consisted of negatively charged particles. He had just discovered electrons. He discovered all of this on a trip from America. Since electrons are so small, he believed that they could only be from inside of the atom. Since Thomson's discovery of the electron, John Dalton's theory that atoms are indivisible had to be changed.
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.
The person who believed everything was made of atoms?
Democratis(lived in 400 b.c)

What theory is that all matter is composed of atoms?
Dalton's Atomic Theory
What is the kinetic-theory?
The theory that states that all atoms are constantly moving

Who didn't have experimental evidence to support his theory of atoms?
The Greek philosopher Democritus first put forward the idea of atoms as an intellectual theory.
What did schrodinger and heisenberg do?
they discovered theory's of atoms
According to Dalton's atomic theory what can atoms do in a chemical reaction?
separate from atoms they are attahed to, and combine with other atoms
What observatin did democritus theory explain?
According to Democritus' theory, atoms cannot be destroyed (an idea similar to the modern theory of the conservation of matter) and they exist in a vacuum or void, which corresponds to the space between atoms. Atoms of a liquid are smooth and round; atoms of a solid are jagged and catch on to each other. Atoms differ only in shape, position, and arrangement.
What is the definition of the atomic theory?
The atomic theory is a scientific theory that states that all matter is composed of individual atoms, which are the smallest units of an element that retain the properties of that element. It also proposes that atoms combine in specific ratios to form compounds.
What did Democritus think the atom was?
Democritus' atomic theory states that atoms are indivisible. That's why they have their name. Atoms is a plural of atom. Atom derives from Atoms. Atoms is greek for INDIVISIBLE. His theory states that atoms cannot be divided any further.
What part of daltons theory was modified after discovery of isotopes?
Atoms may not be changed into other atoms.
