Nitrogen
There are many gases in the atmosphere. a few of them are nitrogen, oxygen, and argon. nitrogen is mixed into the air the most.
At room temperature, any reaction.
When iridium, oxygen, and nitrogen are mixed together, they do not react to form a specific compound. Iridium is a noble metal and does not readily react with oxygen or nitrogen under normal conditions.
Sodium Nitride, whenever you have a salt the Cation is called its normal name 'Sodium' while a 'Ide' is added to the end of the Anion 'Nitrogen' -> 'Nitride'
