Before you determine how an element combine
with another element, you have to know about
Chemical Combination and Electron Transfer.
Let's take magnesium chloride (Mg2Cl) as a case
study Name - Mg CL Atomic number - 12 17
Electronic configuration - 2,8,2 2,8,7 For both
element to attain stable octet there must be
electron share/transfer Mg Cl 2,8,2 -2=2,8 2,8,7
+1 = 2,8,8 2,8,7 +1 = 2,8,8 Explanation÷ Mg
