Lithium nitride facts for kids
Lithium nitride is a special kind of chemical compound. Think of it as a tiny building block made from two different ingredients: lithium and nitrogen. Its scientific formula is Li3N. This means it has three lithium atoms for every one nitrogen atom.

What is Lithium Nitride Like?
Lithium nitride is a solid material that can be red or purple. It's quite special because of how it behaves!
Reactions with Other Substances
When lithium nitride touches water, it reacts quickly. This reaction creates two new substances: lithium hydroxide and ammonia. Ammonia is a gas with a strong smell, like the one you might find in cleaning products.
Lithium nitride is also unique among similar compounds called alkali metal nitrides. It's the only one that stays stable, meaning it doesn't easily break down. It's also a very strong base, which is the opposite of an acid. It can also react with hydrogen to form other compounds called lithium hydride and lithium amide.
How is Lithium Nitride Made?
Scientists usually make lithium nitride by mixing lithium metal directly with nitrogen gas. This is quite unusual! Most other elements don't react with nitrogen gas at normal room temperatures, but lithium does.
Another way to make it is by reacting nitrogen gas with lithium that has been dissolved in sodium metal.
What is Lithium Nitride Used For?
Lithium nitride has a few interesting uses.
Storing Hydrogen
One important use is for storing hydrogen gas. Hydrogen is a clean fuel, and lithium nitride can help hold it safely.
Providing Nitride Ions
It can also be used as a way to get the nitride ion for other chemical reactions. A nitride ion is a charged particle of nitrogen.
Safety Information
Lithium nitride needs to be handled carefully. It is considered toxic and corrosive. This means it can be harmful if you touch it or breathe it in, and it can damage other materials. Remember, it releases ammonia gas when it comes into contact with water, which can be irritating.
