## Introduction: Homemade Post-It Periodic Table

Hi! Welcome to this wonderful tutorial on creating a home-made periodic table, from materials we all have at home! That means there is no extra cost on making this wonderful creation, just will and good mood! Spend your time doing something practical, decorating your closet and saving space and money!

## Step 1: First Things First: Measurements

You will need space. A hell of a lot space. So first measure the size of the post-its you have. In order for this to look good, the post-its should be squares.

Mines are 7,6cmX7,6cm.

The formula you want to use is:

x=a*18 (a: size of square post-its)

y=b*17 (b: size of preferred gap between two post-its)

So the length will be x+y. With 7,6cm post-its and a gap of 0,6cm, it took me a space of 147cm.

Now the height:

z=a*7

t=b*6

I used about 3,2 cm for the gap between the Actinium and Lanthanum lines, so add this (h) to the result.

j=a*2

k=b

So you add z+t+j+k+h, in this case 53,2+3,6+15,2+3,2=75,2cm

A quick measurement needs 147cmX75,2cm.

## Step 2: Next Step: Create the Post-its

Once you have measured, you are ready to go!

A site that will help you find the elements is: http://www.ptable.com/, that's what I used.

Just find the elements, draw them with big letters and include the atomic number and molar mass, as well as the electrons per shell (ex. 2,8,7 for Cl).

You can of course choose your preferred colours for them, I chose YELLOW for the METALS, BLUE for the NONMETALS, GREEN for the METALLOIDS and PINK for the two lines' connection.

Then just glue them to our preferred spot!

## Step 3: YOU ARE READY!

After you have finished these, you are ready to go! You have a big, homemade periodic table!

## Step 4: TIP: I Created the Electrochemical Series of Elements to Help Me.

Try using your brain to figure out more things you can do with post-its. I chose the electrochemical series, and it works absolutely fine, since it is easy to spot elements before or after H(Hydrogen)!
