Iminium

Iminium is a fancy-sounding word that refers to a type of molecule with a nitrogen atom that has a positive charge. Think of it like a little magnet that has a positive side and a negative side. The positive charge on the iminium molecule is like the positive side of the magnet.

Now, the cool thing about iminium is that it is really important in chemistry. It can be used to make all sorts of other molecules that are useful in medicine and industry. Chemists can take different chemicals and react them in a certain way to create iminium compounds. Then, they can use these compounds to create new medicines or materials.

So even though iminium sounds like a big, complicated word, it's actually just a type of molecule that is really important in science.
