Why is it incorrect to say that atoms are indivisible?

Why is it incorrect to say that atoms are indivisible? It is incorrect to say that atoms are indivisible particles because later on it was discovered that atoms can be further divided. It contains some fundamental sub-atomic particles which are electrons, protons, and neutrons. Even neutrons and protons are subdivided into different types. Was this answer helpful?

Does atom mean indivisible? The word atom is derived from the ancient Greek adjective atomos, meaning “uncuttable” or “indivisible.” The earliest concepts of the nature of the atom were debated in ancient India and ancient Greece. We now know that the atom has a nucleus composed of protons and neutrons surrounded by clouds of electrons.

Are atoms indivisible yes or no explain why? All matter is composed of atoms, and atoms are indivisible and indestructible. Elements are composed of identical atoms, but the atoms of each element are different and distinguishable from each other. 2. A compound is composed of atoms from at least two elements.

What is the modern definition of an atom?

An atom is a particle of matter that uniquely defines a chemical element. An atom consists of a central nucleus that is surrounded by one or more negatively charged electrons. The nucleus is positively charged and contains one or more relatively heavy particles known as protons and neutrons.

Who proved that atoms are not indivisible?

Atomic Theory. In 1897, English physicist J. J. Thomson (1856–1940) disproved Dalton’s idea that atoms are indivisible. When elements were excited by an electrical current, atoms break down into two parts.

Who said atoms are indivisible solid spheres?

The question mentions Dalton’s solid sphere model of the atom. John Dalton, one of the scientists among the many scientists and philosophers that proposed models about the atom, proposed his own theory. He proposed that each element is composed of extremely small indivisible particles called atoms.

Who was the first person to say atom?

Democritus was a Greek philosopher who was the first person to use the term atom (atomos: meaning indivisible).

What did JJ Thomson discover?

On April 30, 1897, British physicist J.J. Thomson announced his discovery that atoms were made up of smaller components. This finding revolutionized the way scientists thought about the atom and had major ramifications for the field of physics.

Who believed that atoms were indivisible and indestructible?

In the 5th century B.C. a philosopher named Democritus hypothesized that all matter (plus space and time) is composed of tiny indestructible units, called atoms.

Are atoms really indivisible as proposed by Dalton?

atoms are divisible

READ:  What has higher density liquid or solid?

If we divide one atom we will get sub atomic particles like electrons,protons,neutrons. According to the dalton theory, atoms are indivisible. But this is a limitation of dalton atomic theory as later it was discovered that atoms can be further divided.

Which atomic theory is accepted today?

Dalton’s atomic theory was accepted by many scientists almost immediately. Most of it is still accepted today.

Who rejected the idea of atomism of matter?

Atomism was rejected by leading scientists and philosophers such as Wilhelm Ostwald, Pierre Duhem and Ernst Mach up to the end of the nineteenth century and beyond.

Why was Democritus theory not accepted?

2,500 years ago, Democritus suggested that all matter in the universe was made up of tiny, indivisible, solid objects he called “atomos.” However, other Greek philosophers disliked Democritus’ “atomos” theory because they felt it was illogical.

Did Aristotle believe in atoms?
