Electron Diagram For Magnesium. The nex six electrons will go in the 2p orbital. The second holds 8.
The remaining 2 are placed in the third electron shell which is full when it holds 8 electrons. 800 860 2 kb. Magnesium has 2 electrons in its first shell 8 in its second and 2 in its third check me out.
So far 10 of magnesium s 12 electrons have been used so only 2 remain.
Since 1s can only hold two electrons the next 2 electrons for magnesium go in the 2s orbital. Using electron dot diagrams which show only the outermost shell electrons show how a molecule of oxygen o2 is formed from two oxygen atoms. Magnesium is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column group 2 or alkaline earth metals of the periodic table. The first electron shell of a bohr model holds 2 electrons.
