Atoms of elements are different from one another because the number of protons in an atom which equals to its atomic number. The Bohr model of Hydrogen atom was made in 1913 by Neils Bohr who was a student of Ernest Rutherford. The Bohr model of Hydrogen atom was the very first of atomic structure that was able to correctly explain the radiation spectra of the atomic hydrogen. He studied the planetary model with Ernest Rutherford and noticed that there were problems on Rutherford’s model, so he used spectra of elements to show that electrons were arranged in a concentric circular orbit around the nucleus and they are held together by the electrostatic forces of the negatively charged electrons. He used hydrogen atoms to describe that the positively…show more content…
The quantum theory condition is that the physical quantities change in distinct amounts, rather than continuously amounts. The quantum mechanics which provides a mathematical representation of the actions of energy and matter and the interactions of energy and matter. Bohr developed the theory of the atomic structure that collaborated with Rutherford’s description of the nucleus and with his own proposal that electrons travel in definite orbits around the nucleus and with the theory of quanta that was developed by Albert Einstein and Max Planck. He proposed that electrons only orbit in certain radii, at a definite energy level. Electrons do not emit radiation when orbiting in “allowed” energy levels and they do not spiral downwards. As stated by this idea, an electron which is in the first allowed orbit, has a principle that its quantum number (n) equals to 1 so the lowest state energy is called the ground state of the electron. Each electron has its own allowed energy level when it orbits, and electrons can only move from one energy level to another by absorbing or emitting…show more content…
The first shell can hold up to 2 electrons, second shell can hold up to 8 electrons, third shell can hold up to 18 electrons and the fourth shell can hold up to 32 electrons. The electron configuration is determined by the number of electrons in the outer valance shell and it is used to describe the orbitals which are occupied by the electrons of the atom. The Bohr model of the quantum atom is considered as the cornerstone of quantum mechanics even though it is fundamentally incorrect for all atoms other than hydrogen because Bohr proposed the idea of quantisation for hydrogen’s electronic structure also he was able to explain the emission spectra of hydrogen as thoroughly as other one-electron system. Bohr used spectral evidence to test his atomic theory and he was able to predict that the energy emitted and absorbed by an electron when it changes orbitals would be equivalent to a certain wavelength of electromagnetic radiation and it is possible for it to be measured. He found evidence of his theory of atomic structure which he studied about the spectra and which he chose a specific one which was the hydrogen
