Solution

Solution Steps

Step 1: Understanding Ion Formation

When an element forms a 1-ion, it means that it has gained one electron to achieve a stable electron configuration. This typically occurs when an element is one electron short of having a full outer shell, which is characteristic of elements in Group 17 of the periodic table, also known as the halogens.

Step 2: Identifying the Group

Elements in Group 17 have seven electrons in their outermost shell and need one more electron to achieve a stable noble gas configuration. Therefore, they tend to form 1-ions by gaining an electron.
