(i) Magnesium Interpretation: The number of electrons present in the outermost shell of magnesium is to be stated. Concept introduction: The total number of electrons present in an atom is equal to its atomic number. According to Auf bau principle “the electrons tend to occupy the available orbitals in the increasing order of their energies”. As per this principle the energy of the orbitals in an atom will be in the order 1s > 2s > 2p > 3s > 3p > 4s > 3d > etc. By filling the electrons in this order the number of electrons in the outermost shell can be calculated. To determine: The number of electrons present in the outermost shell of magnesium.
