How to understand Atoms
By: Kianna L.

We all understand atoms; we know the parts of them, they make up everthing, and we know they can be combined in chemical equations. It can get confusing though, can't it? That's why we're here.
Coeffecients are the huge "body guards" who tell exactly how many molecules they're "protecting". There a bit of tattle tales and a bit of protection
What about the small numbers?
The small numbers at the bottom right of the chemical symbol is called subscripts.
Now it's time for the Challenge!
S + HNO3 = H2SO4 + NO2 + H2O
Many students find it difficult to understand why there are parenthesis in chemical equations. One example is 2 Fe+ 3H2SO4 1 Fe2(SO4)3 + 3 H2

What is up with those Parentheses? Who invited them? That's what we're going to find out.
Private Parentheses
The way I understand it is like this. A subscript and its element are in a serious relationship. Subscript is okay being the support system for Element. Of course like any good relationship needs to be protective so chemists thought about putting parentheses would help keep the relationship stable.
Subscripts Objective
What exactly do subscripts do? Subscripts tell the number of atoms in a chemical equaion.
Identify the Coeffecients and Subscribts!
Chemical Equations, we're familiar with them.....Aren't we?
3FeO2+ 7H2= Fe3+O6+H14
7Pb2+8Be2= 4Be5+2Pb7
Balance this Problem...IF YOU DARE!!!!
