Question

electrons dot structure for sodium and magnesium

Answer 1

After that I draw the Lewis dot structure for Sodium. Note: Sodium is in Group 1. Since it is in Group 1 it will have 1 valence electrons. When you draw the Lewis structure for Sodiumyou'll put one "dot" or valance electron next to the element symbol (Na).
hope it helpful...

thank you...

Answer 2

I show you where Magnesium is on the periodic table and how to determine how many valence electrons Magnesium has. After that I draw theLewis dot structure for Magnesium(Mg). Note: Magnesium is in Group 2 (sometimes called Group II or 2A). Since it is in Group 2 it will have 2 valence electrons.Sep 2, 2013
