Binary formula for magnesium and nitrogen


Look for a common number both charges will divide evenly into. When one ion has a charge of 2 and the other has a charge of 3, for example, a good "target" number they will both divide into is 6. All of the examples above contained monoatomic ions ions with ONE element.

But nature is full of polyatomic ions, too. Polyatomic ions are made up of more than one element. Polyatomic ions include ions like NO 3 1- the nitrate ion and CO 3 2- the carbonate ion.

Here is a list of common polyatomic ions and their charges. The idea of charge balancing compounds with polyatomic ions is the same. You just need to be careful about using parentheses as needed.

The general rule is: If you only need 1 of the polyatomic ions then you don't need to surround them with a parentheses. If you need 2 or more of a polyatomic ion then you do need to put them in parentheses so it's clear which subscript belongs to the polyatomic ion and which subscript is there as the charge balancing "inventory" number. Here are some example:. Out of desperation and curiosity he called it the "make the maximum number of mistakes" approach [2] , he added some magnesium wire to the hexagonal boron nitride and gave it the same pressure and heat treatment.

When he examined the wire under a microscope, he found tiny dark lumps clinging to it. These lumps could scratch a polished block of boron carbide , something only diamond was known to do.

From the smell of ammonia, caused by the reaction of magnesium nitride with the moisture in the air, he deduced that the magnesium metal had reacted with the boron nitride to form magnesium nitride, which was the true catalyst. When isolating argon , William Ramsay passed dry air over copper to remove oxygen and over magnesium to remove the nitrogen, forming magnesium nitride.
