Question

Which root word of the binary ionic compound ends with -ide

Answer 1

In binary ionic compounds, the names of nonmetals (anions) end with "-ide." The root word typically comes from the name of the nonmetal.

For example:

Chlorine becomes chloride.

Oxygen becomes oxide.

Sulfur becomes sulfide.

So, in the context of binary ionic compounds, the root word that ends with "-ide" is the name of the anion (nonmetal).
