Match the element in column A with thevalency exhibited by the element

1.	Match the element in column A with thevalency exhibited by the element given in column B{:(,"Column A",,,"Column B"),((A),"Neon",(),(a),""4),((B),"Oxygen",(),(b),""3),((C),"Potassium",(),(c),""2),((D),"Boron",(),(d),""1),((E),"Silicon",(),(d),""0):}
Answer» `ATOB,"" Btoc," " Ctod, " " Dtoe," " Etoa` `Atob,"" Btoc," " Ctoa, " " Dtoe," " Etod` `Atoe,"" Btod," " Ctoa, " " Dtob," " Etoc` `Atoe,"" Btoc," " Ctod, " " Dtob," " Etoa` Solution :`Atoe` Atomic NUMBEROF neon is 10 and electronic configuration 2 , 8 valency is zero. `Btoc` Atomic numberof oxygen is 8 and electronic configuration 2 , 6 valency= 8 - 6 = 2 `Cto d` Atomic number of potassium is 19AND electronic configuration is 2 , 8 , 8 ,valency = 1 `Etoa` Atomic number of SILICON is 14 and electronic cofiguration is 2 , 8 , 4 valency = 4
