Question

question
what is the name of the compound k₂o?
a. potassium oxide
b. potassium(i) oxide
c. potassium oxylate
d. potassium(ii) oxide

Explanation:

Step1: Analyze the compound \(K_2O\)

\(K_2O\) is an ionic compound. Potassium (\(K\)) is a metal with a +1 oxidation state in this compound. Oxide (\(O^{2 -}\)) is the non - metal part.

Step2: Naming ionic compounds

For ionic compounds, we name the metal first (potassium) and then the non - metal (oxide). Since potassium has a fixed oxidation state of +1 in this common ionic form, we don't need to specify the oxidation state in parentheses (as in some transition metal compounds where oxidation states can vary). “Oxylate” is not a correct term for \(O^{2 -}\).

Answer:

A. Potassium oxide
