Draw the electron dot diagram and structure of
(b) magnesium chloride
Open in App
Solution
Electronic configuration of Magnesium (atomic number = 12) is 2, 8, 2 and that of chlorine atom (atomic number = 17) is 2, 8, 7. So, magnesium will lose two electrons to each of the chlorine atom in order for every atom to complete its octet.
