# What is the correct name for Li_3N?

Dec 6, 2016

Well, I'd call it $\text{lithium nitride}$.....

#### Explanation:

And how does it react with water?

Here's my thought process:

• $\text{Li}$ is lithium, and $\text{N}$ is nitrogen.
• $\text{Li}$ is on the first column of the periodic table, and $\text{N}$ is three columns away from the noble gases.

$\implies$ $\text{Li}$ is a metal and $\text{N}$ is a nonmetal.
$\implies$ $\text{Li"_3"N}$ is anticipated to be an ionic compound, where ${\text{Li}}^{+}$ is the cation and ${\text{N}}^{3 -}$ is the anion.

$\implies$ The name of the anion, ${\text{N}}^{3 -}$, will end in "-ide" and you will drop the "-ogen" to replace it with "-ide".

$\implies$ Append "lithium" at the beginning, because lithium is the cation.

$\implies$ Lithium nitride
