Question

group 17 elements are called halogens. halogen means \salt former,\ derived from the greek words halo- (\salt\) and -gen (\formation\). halogens bond with metals to form a wide variety of ionic compounds (salts). three pure halogens: chlorine gas, liquid bromine, and solid iodine. complete the statement. to produce stable ions, halogens electron(s) to form ions with a charge. image credit show periodic table

Explanation:

Step1: Analyze halogen electron - configuration

Halogens have 7 valence electrons.

Step2: Determine electron - gain behavior

To achieve a stable octet (8 - electron outer - shell), they gain 1 electron.

Step3: Calculate ion charge

When an atom gains 1 electron, it forms an ion with a - 1 charge.

Answer:

To produce stable ions, halogens gain 1 electron(s) to form ions with a - 1 charge.
