Question

Make a schematic atomic structure of Magnesium or Phosphorus.

(Given: number of protons of Magnesium 12, Phosphorus 15).

Accepted Answer

The number of protons in magnesium is 12 and the number of electrons also be 12, as an atom is neutral. The maximum number of electrons that could be present in a shell is given by the rule $2 n^{2}$ , where n is the shell number. That is the first shell K shell can accommodate a maximum of 2 electrons, second shell L can accommodate a maximum of 8 electrons and the remaining 2 electrons will enter into M shell. Thus, the electronic configuration of the magnesium is 2,8,2.

The number of protons in phosphorus is 15 and the number of electrons also be 15 as an atom is neutral in nature. The maximum number of electrons that could be present in a shell is given by the rule $2 n^{2}$ , where n is the shell number. That is the first shell K shell can accommodate a maximum of 2 electrons, second shell L can accommodate a maximum of 8 electrons and the remaining 5 electrons will enter into M shell. Thus, the electronic configuration of the phosphorous is 2,8,5.
