Explain the following of sodium chloride. |
| Answer» Solution :Sodium (Z=11)has electronic configuration of2 , 8 , 1 . By losing one ELECTRON , it forms`Na^(+)`ion which attains the configuration of neon that is 2 , 8. CHLORINE(Z =17 ) has electronic configuration of 2 , 8 , 7 . By gaining one electron it forms `Cl^(-)`ion which attains the configuration of argon that is 2 , 8 , 8 . since `Na^(+) andCl^(-)`ion carry opposite charges a strong force of attraction binds the TWO IONS together . thus , the compound sodium CHLORIDE is formed. | |
