Question

How do we name the anions of representative elements?

A) Add "-ide" to the element name
B) Add "-ate" to the element name
C) Add "-ite" to the element name
D) Keep the element name unchanged

Answer 1

The anions of representative elements are named by adding the suffix "-ide" to the stem of the element's name, followed by the word ion. The correct answer to how we name the anions is A) Add "-ide" to the element name.

Step-by-step explanation:

The correct way to name the anions of representative elements is by adding the suffix "-ide" to the element name, followed by the word ion. Therefore, the answer is A) Add "-ide" to the element name. This rule applies to monatomic anions, which are ions consisting of a single atom with a negative charge.

For example, the anion formed by chlorine will be called chloride ion (Cl⁻), oxygen forms the oxide ion (O²⁻), and sulfur forms the sulfide ion (S²⁻). It's important to remember that while naming cations you just use the element name followed by the word ion, for anions, you replace the ending of the element's name with "-ide" and then add ion. This naming convention is crucial for correctly identifying and communicating about different ionic compounds.
