Questions: Group 17 always has ions with a charge of -1

Transcript text: Group 17 always has ions with a charge of $-1$

Solution

Solution Steps

Step 1: Identify the Group 17 Elements

Group 17 elements in the periodic table are known as the halogens. These elements include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).

Step 2: Determine the Common Ion Charge for Halogens

Halogens typically gain one electron to achieve a stable electron configuration, similar to the nearest noble gas. This results in a negative charge.

Step 3: Confirm the Charge of Halogen Ions

When halogens gain one electron, they form ions with a charge of $-1$.

Final Answer

$\boxed{-1}$
