NH4Br, the 4 is supposed to be small and in the bottom right corner. I don't get it. How did they get those letters and numbers?

NO TELL ME HOW YOU WRITE IT AS A COMPOUND!!!!!

NH4Br
Here is where the numbers and letters came from:
The compound is called Ammonium Bromide. The Ammonium ion is composed of one Nitrogen atom and four Hydrogen atoms. The typical way to write this is NH4+ where the 4 is subscript (small and down) and the + is superscript (small and written up.
The Bromide is usually written as Br- where the minus is superscripted. The + and - cancel each other when you write the compound:
NH4Br

It's not an element. It's a representation of a molecule using Lewis notation. It's ammonium bromide. Each molecule is formed from a positive ammonium ion, NH3, with an ionic bond to a negative bromine ion, Br. The notation just tells you the component atoms, 4 hydrogen and one each of nitrogen and bromine. As soon as you learn a little chemistry, you can recognize the rest.

It is a molecule w/ 1 Nitrogen, 4 Hydrogen, & 1 Bromide atoms.
They can tell by analysis of other reactions, or through balancing the reaction if the initial chemcals are known.
What goes in must come out.

You are correct that the 4 is subscripted.
This is ammonium bromide. You form it by reacting ammonia, NH3, with HBr.
The numbers mean that there is one nitrogen atom (you don't write 1, it is assumed if not written), four hydrogen, and one bromine atom. You could write N1H4Br1 but the convension is to only write numbers greater than one.

It's not an element, it's a compound.
1 nitrogen
4 hydrogen
1 bromine.
As a guess, ammonium bromide?
I was so impressed it got it right, I went and looked up what it is used for. You may (or many not) find this interesting

the letters stand for the name of the element capitol letters in beginning and lowercase next the #'s stand for how many atoms of that element are in that compound.
EX:
H2O is hydrogen oxide (water) water had 2 hydrogen atoms and 1 oxogen atom
or
Mg4O would be magmesium oxide with 4 magnesium atoms and 1 oxogen atom
oh and that compoud is Amonium Brombine!!!

If you use Microsoft Word go to Format, Font, and select subscript.
