carbon (C)	fluorine (F)	lithium (Li)	sodium (Na)	oxygen (O)	nitrogen (N)	sulfur (S)	hydrogen (H)

To get started, we need to know how to read the different parts of a chemical equation.
 

left side of equation	produces	right side of equation
reactant(s)	====>	product(s)

Na + F2 ===>  NaF  In this case, on the left side of the equation, a single sodium atom is by itself, and we would draw it like this:

Also on the left side of the table, we see Fluorine, but it has a "2" subscripted after it.  This means that there are two Fluorine atoms present, and that they are bonded together.  We would draw them like this:

Finally, we see on the right side of the equation that Sodium and Fluorine have gotten together.  Since there are no subscripted numbers, it means that one atom of Sodium bonds with one atom of Fluorine, like this:

The drawing for the whole equation would look like this:

    +    ===>

(+2)Draw this equation:    C    +    O₂   ===>    CO₂
 
 
 

(+2)Draw this equation:    Na    +    CO₂   ===>    Na₂O    +    C
 
 
 

(+2)Draw this equation:    H₂O₂   ===>    H₂O    +    O₂
 
 
 

The three equations you drew above are each a different type of reaction.  The three types of reactions are:

synthesis reactions, where simpler reactants produce more complex products
decomposition, where more complex reactants are separated into simpler components
replacement, where atoms swap positions with other atoms
