Question
dentify the element on the basis of the electronic configuration.1𝑠22𝑠22𝑝63𝑠21s 2 2s 2 2p 6 3s 2 A.NaB.MgC.AlD.K
Solution
The electronic configuration you provided is 1s2 2s2 2p6 3s2. This configuration corresponds to the element Magnesium (Mg). Here's why:
- The sum of the superscripts in the configuration is the atomic number of the element. In this case, 2 (from 1s2) + 2 (from 2s2) + 6 (from 2p6) + 2 (from 3s2) equals 12.
- The atomic number 12 corresponds to Magnesium (Mg) on the periodic table.
So, the correct answer is B. Mg (Magnesium).
