Questions: Write the name for Mg(IO3)2.

Transcript text: Write the name for $\mathrm{Mg}\left(\mathrm{IO}_{3}\right)_{2}$.

Solution

Solution Steps

Step 1: Identify the Cation and Anion

The chemical formula $\mathrm{Mg}\left(\mathrm{IO}_{3}\right)_{2}$ consists of two parts: the cation $\mathrm{Mg}^{2+}$ and the anion $\mathrm{IO}_{3}^{-}$.

Step 2: Name the Cation

The cation $\mathrm{Mg}^{2+}$ is magnesium. Magnesium is a Group 2 element and typically forms a $2+$ charge, so it is simply named "magnesium."

Step 3: Name the Anion

The anion $\mathrm{IO}_{3}^{-}$ is known as iodate. The naming convention for polyatomic ions ending in "-ate" is to use the root of the element (iodine) followed by the suffix "-ate."

Step 4: Combine the Names

Combine the names of the cation and anion to form the name of the compound. Since magnesium typically has a $2+$ charge, there is no need to specify the charge in the name.

Final Answer

\[ \boxed{\text{Magnesium iodate}} \]
