Making a Model Atom

Later on edit:

I majorly screwed up with this.
There are so many things wrong with this.
Nitrogen has seven electrons; Beryllium has four.
If I talk about Beryllium in this post using a 2,5, kinda pattern, I screwed up, Nitrogen has that pattern, Beryllium has an electron pattern of 2,2.
Ignore any scientific explanation and the diagram, I know I screwed up the diagram majorly, so you shouldn't really trust the science either

Aim: To make a model atom.

Equipment:

Paper
Tape
Beads
Blue Tack
String

Method:

With these instructions, you will be making a model of the atom Beryllium, this particular atom has four protons (silver beads), four neutrons (gold beads), and seven electrons (black circles).

1. Take a piece of paper and fold it into quarters. Cut three quarter circles from the folded corner. Throw ring two out. You don't need it.
2. Next, take your rings, on the smaller ring, draw two small black circles connected to one another. On the second larger paper ring, draw two pairs of circles and a singular circle by itself. Make sure to set these away from each other as shown in the results.
3. Put the rings aside and take out your blue tack, stick all eight of the beads on, whatever the colour, it doesn't matter, as long as four are one colour and the other four are another. This is your nucleus.
4. Take your string and press it into the blue tack, making sure it sticks on without either piece falling.
5. Take your smallest ring and flip it upside down so you can't see the beads. Take the blue tack, beads and string and align it in the creases of the paper and in the middle of the ring. Use the tape to stick the string to the paper on both sides.
6. Repeat with the larger ring.
7. Grab your nearest periodic table and design your own little label for the atom, like you'll see mine has, I personally went with a basic one.

What makes up the atom? + Plus answering other things!

The three main particles make up the atom, including electrons, protons and neutrons. While the protons and neutrons are located in the nucleus, the electrons form shells, wanting to form a full outer shell to become an ion. From what I know, atoms have three shells, two outer and the first shell. The first shell can only hold two electrons, once it has that many electrons, the electrons go to the next shell, which can hold a maximum of eight, if that is at its maximum capacity, it goes to the next shells, all of which, if there are more than two outer shells, can hold a maximum of eight. The example above, Beryllium, does not have a valance shell (full outer shell), and it would gain one by either losing or gaining electrons. Since Beryllium's pattern is 2,5, it's best bet would be to gain electrons, therefore gaining a valance shell and becoming an ion. The way that it would gain these electrons would be through a chemical reaction. During a chemical reaction, atoms either lose or gain electrons to gain a valance shell.

The major differences between the particles in an atom are their sizes, charge, and place. As discussed, the protons and neutrons are in the nucleus, while electrons surround them to form the shell or shells. You may think that the particles are all the same sizes, and while protons and neutrons are the same sizes, however, the electron sets itself away from them again by being a two-thousandth of their size. The only thing that I know that sets the protons and neutrons apart is their charge, protons are filled with a positive charge, neutrons have no charge, and electrons have a negative charge. Due to this, the atom Beryllium's whole charge is -3, however, after becoming an ion with a valance shell, it would become -6.
