What is the charge of a chloride ion?
A
-2
B
0
C
+1
D
-1
Verified step by step guidance1
Recall that a chloride ion is formed when a chlorine atom gains an electron.
Understand that chlorine (Cl) is a halogen with 7 valence electrons and tends to gain 1 electron to achieve a full octet.
When chlorine gains 1 electron, it acquires an extra negative charge, resulting in a charge of -1.
Therefore, the charge of a chloride ion (Cl⁻) is negative one, written as -1.
This explains why the correct answer is -1, not -2, 0, or +1.
