- an atom has a positive charge in the nucleus and a negative charge in the electron cloud; the atom is normally neutral
- these charges are separated

Atoms are made up of the smallest form of matter
Michael Faraday's main contribution to atomic theory was his work on electrolysis, which demonstrated that chemical compounds are composed of discrete particles and that these particles carry an electric charge. This provided evidence for the existence of atoms and laid the foundation for the development of the modern atomic theory.
Atoms will go further when we study about those. We cannot give any conclusion for this. But, we must give a temporary conclusion. That is atoms play a key role in the universe it is needed t0 experiment on those.
there were many scientists that contributed towards it but Joseph j. Thomson, Hans geiger, ernest marsden. ernest Rutherford, Henry moseley and James chadwick all made key discoveries and are the main scientists behind the theory.Alfred Nobel,Mendeleev and Neil Bhorbecause theire are the great scientistChadwick explain the atomic theoryniels hendrik bohrmitchell creech
One main point of Dalton's atomic theory is that all matter is composed of indivisible particles called atoms, which cannot be created or destroyed in chemical reactions. Dalton proposed that atoms of a given element are identical in mass and properties, while atoms of different elements differ in these characteristics. This theory laid the foundational understanding of chemical reactions as the rearrangement of atoms.
Actually, Albert Einstein is credited with formulating the theory of relativity, not John Palton. The theory of relativity revolutionized our understanding of space, time, and gravity, with two main branches: special relativity and general relativity.
John Dalton is famous for his work in developing the atomic theory of matter, which states that all matter is composed of tiny, indivisible particles called atoms. He also pioneered the concept of atomic weights and made significant contributions to the field of chemistry.
The main factors that determine how strongly a beam is attenuated arethe energy of the incident photons;the atomic number (Z) of the medium (absorber material);the density of the medium;as well as the thickness of the medium
Yes, Dalton's atomic theory is still relevant today. While some parts of his theory have been modified or expanded upon based on new scientific discoveries, the main principles of atoms being the building blocks of matter and elements being composed of individual atoms remain key concepts in modern atomic theory.
Attribution theory refers to an individual's perception of the main causes of life events, whether attributing them to internal or external factors, stable or unstable factors, or controllable or uncontrollable factors.
This theory considers intelligence as a combination of numerous separate elements or factors, each one being a minute element promoting a specific type of activity.THORNDIKE is the main propagator of this theory.
