Atomic Theories According to Experts (Full Discussion) – In this world there are many fine particles that are so small that we cannot see them with the naked eye or without the aid of a visual aid.

Inside the particles that we see using the tools are very small. It is a core that is inside the particle. the particle can no longer be separated or cannot be divided again.

Small particles scattered throughout the universe can be called atoms. Atom has an understanding or theory that is very much given by experts or scientists. To understand what the theory of atoms will be explained as follows.

Atomic Theories According to Experts (Full Discussion)

Let's discuss atomic theory carefully.

Atomic Theories

There are so many theories about atoms because experts really like and are interested in atoms. Atom itself is a particle that there are many in this universe. Because of that unique part that makes scientists and experts give their opinions about atoms, so many theories about atoms emerge.

Atomic Theories According to Experts

Atom according to experts we can see as follows:

1. Dalton's Atomic Theory

Dalton gave an explanation of the atom as follows:

  1. All substances that are made up of very small particles are called atoms.
  2. Atom is a particle that can no longer be divided or broken down.
  3. Atoms cannot be destroyed nor can they be created or created.
  4. The atoms in an element are identical in size, shape, and other properties.
  5. The atoms in a different element have different properties.
  6. The atoms in the compound will combine and form small integers.

2. Demicritus's Atomic Theory

The atomic theory given by Demicritus is as follows:

When an object is broken and divided continuously, a part will be obtained that is no longer possible to be divided again. This part is an atom or atomos which means it cannot be divided again.

3. Thomson's Atomic Theory

Thomson gave an explanation of the atom as follows:

The atom consists of a mass that has a spherical shape with a large positive charge and is evenly distributed, while the electrons are scattered randomly on the surface. (which is similar to the raisins attached to the bread) this model is known as the raisin bread model and in one case, the electrons can serve to neutralize the atoms the.

4. Bohr's atomic theory

Bohr's atomic theory is as follows:

  1. The electrons move around the atomic nucleus in circular paths or orbits or energy levels.
  2. The energy contained in an electron in its orbit is constant.
  3. When an electron jumps from a low energy level or deep orbit to high energy level that is in the outer orbit then the electron will absorb some energy.
  4. When an electron jumps from a high energy level or outer orbit to a low energy state in the inner orbit, the electron will be able to radiate some energy, which means that the photon will be able to emit.
  5. The spectrum of light originating from an electron is in the form of a line spectron.
  6. The angular momentum present in the electron is an even multiple of h/2π
  7. All chemical reactions are a combination or separation of atoms.
  8. The molecule that is owned by a compound consists of combining two or more atoms.

5. Rutherford's Atomic Theory

According to him the atom has the following causal theory:

  1. The atomic nucleus has a positive charge with a diameter of about 10^-13 cm.
  2. All of the atomic mass that has been concentrated in the atomic nucleus, while the electrons that have a negative charge will surround the atom in different circular orbitals.
  3. The force from the electrostatic or colomb force will be able to provide a centripetal force to the electrons when they surround the atomic nucleus.

6. De Broglie's Atomic Theory

The atomic theory he gave was as follows:

Atoms themselves have particle properties but electrons also have wavy properties. This theory is a refinement of the atomic theory which is owned by Bohr.

Here's an explanation about Atomic Theories According to Experts (Full Discussion) explained by aroundknowledge.co.id. Many explanations about atomic theory will be able to provide many references to what exactly the atom is. Hope it is useful.
