The electronic configuration of magnesium is 2, 8, 2. From this it is understood that the valence shell of Magnesium is ......................... |
|
Answer» The VALENCY is 0 and the ELECTRON in external most shell is 2. Magnesium is component 12 and has a place with GROUP 2 of the Periodic Table. A component in Group 2 has TWO valence electrons. Since the 3s² electrons are the PERIPHERAL electrons, magnesium has two valence electrons. |
