5 Theories on Atomic Structures
Dalton's atomic model
John Dalton, an English scientist and chemist, proposed it.
It claimed that tiny, indestructible particles known as "atoms" make up matter.
This idea states that all substances are composed of indivisible, unbreakable atoms.
Atoms of the same element have the same size and mass, whereas atoms of different elements don't.
Thomson's model of atom
The idea was advanced by J.J. Thomson.
Additionally known as the plum pudding model.
The interior structure of an atom was theoretically explained by this paradigm.
Thomson claimed that an atom looked like a sphere of positive charges with electrons dispersed inside.
An atom is electrically neutral in this situation because the magnitudes of the positive and negative charges are equal.
Bohr's Model
Neil Bohr, a Danish scientist, proposed it.
Rutherford model is comparable to it.
In the Bohr model, which resembles a solar system of planets, negatively charged particles orbit a positively charged nucleus.
Between these positive and negative particles, there is a Coulomb force.
Erwin Schrödinger, an Austrian scientist, proposed it.
It claimed that by mathematically characterizing atoms as matter waves, the behavior of atoms may be explained more precisely.
The quantum mechanical or wave mechanical model is what this one is called.
According to this idea, an atom has a tiny, compact, positively charged core called the nucleus, where almost all of the mass is concentrated. The negatively charged electrons then orbit the nucleus like planets do the sun.
This model was developed since the Thomson model was unable to adequately account for some facts related to the atomic structure of elements.
Ernest Rutherford, a British scientist, proposed it.
