The overall charge on sodium chloride formed by the combination of an anion (Cl-) and a cation (Na+) is
-1 charge
+1 charge
+ 2 charge
None of these.
The +1 charge of Na is cancelled by -1 charge on Cl in the formation of NaCl compound. So NaCl compound is electrically neutral.
The overall charge on the 'sodium chloride' compound formed by the combination of Cl− ion and Na+ ion is
The value of x, y and z in the following equation are:
xH2+yO2→zH2O
