Is the atom an indivisible sphere?

1. All matter is composed of indivisible and indestructible atoms. Dalton’s Model of the atom was a solid, indivisible, indestructible sphere. It would be almost 100 years before scientists were able to expand on Dalton’s Model.

Who said that atom is indivisible?

Dalton’s atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that all matter is made of atoms, which are indivisible.

Was wrong about atoms being indivisible?

The indivisibility of an atom was proved wrong: an atom can be further subdivided into protons, neutrons and electrons. According to Dalton, the atoms of same element are similar in all respects. However, atoms of some elements vary in their masses and densities. These atoms of different masses are called isotopes.

Are atoms still indivisible?

Atoms are not indivisible or indestructible. While all atoms of a given element do have the same number of protons which gives them a great deal of their chemical character, they can vary in their mass and properties by changes in their number of neutrons and electrons.

How did scientists prove that atoms are indivisible?

Atom was the indivisible particle up till Dalton’s theory. Then in 1897 when J J Thomson discovered electrons he stated that atoms are divisible. Then new subatomic particles proton, electron, and neutron were discovered so now atom is divisible.

Are atoms indivisible and indestructible?

Are elements indivisible?

Elements are composed of minute, indivisible particles called atoms. Atoms of the same element are alike in mass and size. Atoms cannot be created, destroyed, or subdivided.

Is an atom divisible or indivisible justify your answer?

An atom is defined as the smallest individual particle of a matter. Atom was the indivisible particle up till Dalton’s theory. Then in 1897 when J J Thomson discovered electrons he stated that atoms are divisible. Then new subatomic particles proton, electron, and neutron were discovered so now atom is divisible.

Are atoms really indivisible as proposed by Dalton or are there smaller constituents inside the atom?

atoms are divisible If we divide one atom we will get sub atomic particles like electrons,protons,neutrons. According to the dalton theory, atoms are indivisible.
