To find the electronic configuration of the element placed in the 2nd Group and 3rd Period of the Periodic Table, we can follow these steps: ### Step 1: Identify the Element The element in the 2nd Group and 3rd Period of the Periodic Table is Magnesium (Mg). This is because Group 2 contains alkaline earth metals, and the 3rd Period includes elements like sodium (Na), magnesium (Mg), and aluminum (Al). **Hint:** Remember that the groups are vertical columns and periods are horizontal rows in the periodic table. ### Step 2: Determine the Atomic Number ...
