To understand this concept you need to keep one basic idea in your mind:
In each Period in the P.T as you move to the right the atomic radius of elements decreases this is because as you move Right there is more Protons pulling in the outer electron shell resulting in a smaller atomic radius.

What is atomic radius?
This periodic table shows the radius of atoms arranged by their placement in the periodic table.
This is just a regular periodic table.
To understand atomic radius we need to look at it in periods so we will chose the 4th period on the periodic table. Below is a model showing the differences between two atoms in the same period
In fact our suspensions are correct the number of protons is directly related to the atomic radius of a atom. this means that we can take two atoms from the same period lets call them A and B for simplicity. lets say they are both in the 4th period and atom A has 29 protons and Atom B has 22 protons we can assume that B will have a larger atomic radius. this is because more protons means more pull on the outer electron shell. So because Atom A has more protons than B we can say that A will have a smaller atomic radius because it has more protons to pull on the outer electron shell.

Materials needed
1x Ballon
rubber bands
Execution
Blow up the balloon
wrap balloons with rubber bands
evaluate how the balloons are affected by the rubber bands
Understanding the model
In this model we are using rubber bands as Protons and balloons as they are atoms. It is important to Realize that as you add rubber bands the radius of the balloon (the atom) decreases. This can be used as a model to represent atomic radius in periods because as a atom (or the Balloon) gains Protons (or rubber bands) the atomic radius will decrease. A clear representation of this is if you compare a balloon with 19 rubber bands on it Vs. a Balloon with 36 rubber bands you will realize the radius of the balloon with more 36 rubber bands will have a smaller atomic radius than the balloon with 19 rubber bands. This represents the main idea of this concept because an as shown above a atom with 36 protons will have a smaller atomic radius than a atom with 19 protons.
