#### Answer

The name of $Mn(OH)_2$ is: "Manganese (II) hydroxide".

#### Work Step by Step

1. Identify the positive ion, and name it. $Mn^{2+}$ is the positive ion. So, the first name of the compound will be: "Manganese (II)"; ** Most of the transition metals have more than 1 ion, so we must put a number to indicate the charge. 2. Identify the negative ion, and name it. $OH^-$ is the negative ion. As we can see in Table 2.2 (Page 58), this ion is called "hydroxide". 3. Putting those two names together: Manganese (II) hydroxide.
