Name: Date: period: Bohr Model Practlco number of electrons on the line. Then color the correct number of electrons for Bohr model, description of the structure of atoms, especially that of hydrogen, proposed (1913) by the Danish physicist Niels Bohr. The Bohr model of the atom, a radical departure from earlier, classical descriptions, was the first that incorporated quantum theory and was the predecessor of wholly quantum-mechanical models. The Bohr model and all of its successors describe the properties of atomic electrons in terms of a set of allowed (possible) values. Atoms absorb or emit radiation only Bohr Diagrams 1) Check your work. 2) You should have 6 total electrons for Carbon.

Magnesium, Mg, has 12 electrons distributed as: 1st shell 2 electrons, 2nd shell 8 electrons and third shell 2 electrons. See how to draw here: Het atoommodel van Bohr is een in 1913 door Niels Bohr geïntroduceerde theorie die de opbouw van atomen beschrijft. Bohr modificeerde het atoommodel van Rutherford door het invoeren van kwantiseringen, gebaseerd op de theorie van Planck over de kwantisering van straling.

Bohr Diagrams. Bohr diagrams show electrons orbiting the nucleus of an atom somewhat like planets orbit around the sun. In the Bohr model, electrons are pictured as traveling in circles at different shells, depending on which element you have.
