HOW TO FIND ELECTRONIC CONFIGURATION

To calculate an electron configuration, divide the periodic table into sections to represent the atomic orbitals, the regions where electrons are contained. Groups one and two are the s-block, three through 12 represent the d-block, 13 to 18 are the p-block and the two rows at the bottom are the f-block.

• Magnesium has atomic number 12. It will be distributed in K, L, M shell in the following way: K shell can accommodate a maximum of 2 electrons.
• Magnesium has atomic number 12. It will be distributed in K, L, M shell in the following way: K shell can accommodate a maximum of 2 electrons. L shell can accommodate a maximum of 8 electrons and
• Magnesium has atomic number 12. It will be distributed in K, L, M shell in the following way: K shell can accommodate a maximum of 2 electrons. L shell can accommodate a maximum of 8 electrons and M shell will accommodate 2 electrons
• Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column of the periodic
• So the configuration becomes 2,8,2.
