WebDec 17, 2015 · Dec 17, 2015. Magnesium has 12 protons and 12 electrons. The first electron shell of a Bohr model holds 2 electrons. The second holds 8. So far, 10 of magnesium's 12 electrons have been used, so only 2 remain. The remaining 2 are placed in the third electron shell, which is full when it holds 8 electrons. WebBohr and Bury proposed the following rules for electron distribution. Rule 1: The maximum number of electrons present in a shell is given by the formula 2n 2, where 'n' is the shell number. Rule 2: Each energy level or electron shell is further divided into sub shells. The maximum number of electrons that can be accommodated in each sub shell is 8.
