positive charge on an ion would bind to Cl-
Explanation:
The chloride ion Cl- will bind to positively charged ion or cation to form an ionic bond or covalent bonds.
In ionic bond formation Chloride ion attracts the positively charged ion towards itself to complete its octet.
as in case of NaCl and CaCl2.
Atom becomes positively or negatively charged when the neutral atoms gain or loose when electrons and the proton and electron numbers get differ.
Na+ will give 1 electron to Cl- to form ionic bond.
