Question

group 1 metals can bond with group 17 nonmetals to form ionic compounds. an example is potassium iodide, which is often added to sodium chloride to make iodized table salt. eating iodized table salt helps prevent iodine deficiency in the body. complete the statement. to produce a neutral ionic compound, one ion from group 1 is needed for every ion(s) from group 17.

Explanation:

Step1: Determine ion charges

Group 1 metals form +1 ions, group 17 non - metals form - 1 ions.

Step2: Balance charges for neutral compound

To get a neutral ionic compound, the total positive charge must equal the total negative charge. Since the charge of a group 1 ion is +1 and the charge of a group 17 ion is -1, one +1 ion will balance one -1 ion.
