Explain the formation of (i) sodium ion, and (ii) chloride ion, from their respective atoms giving the number of proton and number of electrons in each one of them. What is the reason for positive charge on a sodium ion and a negative charge on a chloride ion ?

With reference to formation of compounds from atoms by electron transfer - electrovalency, state the basic steps in the conversion of sodium & chlorine atoms to sodium & chloride ions leading to the formation of the compound - sodium chloride. [electronic configuration of: Na = 2,8,1 & Cl = 2,8,7]
