Question : Negative ions that consist of a single atom are named by adding the suffix _______ to the stem of the element.
Option 1: -onium
Option 2: -ide
Option 3: -ic
Option 4: -ous
Correct Answer: -ide
Solution : The correct option is -ide .
When negative ions consist of a single atom, they are named by adding the suffix "-ide" to the stem of the element. These negative ions are called " anions."
- Chlorine (Cl) forms a chloride ion
- Oxygen (O) forms an oxide ion
- Nitrogen (N) forms a nitride ion
In each case, the "-ide" suffix is added to the elemental name to denote the negatively charged ion that consists of a single atom of that element.
