    Answer:

    Their charge is —1

    Explanation:

    Halogens form ionic compounds by receiving 1 electron from a metallic atom to obtain their octet configuration. This is clearly seen when sodium(Na) react with chlorine(Cl) to form sodium chloride (NaCl) as shown below:

    Na —> Na+ + e-

    Cl + e- —> Cl-

    Combining both equation together, we have:

    Na + Cl + e- —> Na+ + Cl- + e-

    Eliminate the e-

    Na + Cl —> Na+Cl-

    From the ionic equation we can see that the charge of the Halogen (Cl) is —1
