ELECTRONIC CONFIGURATION AND ITS RELATION WITH THE PERIODIC TABLE.
Introduction
It will be realized a description ofdifferent theories and atomic models through the history and how the researches came to the actual model. We are going to learn the quantum model consisting and the electronic configuration.

Theories andatomic models
BOHR’S MODEL
Niels Bohr proposed the Bohr Model of the Atom in 1915. Because the Bohr Model is a modification of the earlier Rutherford Model, some people call Bohr's Model theRutherford-Bohr Model. The modern model of the atom is based on quantum mechanics. The Bohr Model contains some errors, but it is important because it describes most of the accepted features of atomictheory without all of the high-level math of the modern version. Unlike earlier models, the Bohr Model explains the Rydberg formula for the spectral emission lines of atomic hydrogen.
The Bohr Model isa planetary model in which the negatively-charged electrons orbit a small, positively-charged nucleus similar to the planets orbiting the Sun (except that the orbits are not planar). Thegravitational force of the solar system is mathematically akin to the Coulomb (electrical) force between the positively-charged nucleus and the negatively-charged electrons.
RUTHERFORD ATOMIC MODEL
Rutherfordatomic model,  description of the structure of atoms Proposed (1911) by the British physicist Ernest Rutherford . The model Described the atom as a tiny, dense, positively charged core called anucleus, in nearly all the mass Which is Concentrated, around Which the light, negative Constituents, called electrons, circulate at some distance, much like planets revolving around the Sun . The...
