How will identify the cations and anions. And the charge of the formula
Asked by | 23rd Mar, 2012, 10:17: AM
The atoms in molecules bond to one another through "sharing"of electrons. Ionic compounds on the other had have atoms or molecules that bond to one another through their mutual attraction.
The composition of ionic compounds is determined by the requirement that the compounds must be electrically neutral. That is that the charges of the cations and anions must balance or 'cancel" out one another. For example consider sodium cations (Na+) and Chlorine anions (Cl-). Sodium has a positive 1 charge and chloride has a negative 1 charge. Thus one sodium cation cancels one chloride anion resulting in the formula Na1Cl1 or NaCl.
