How to create a model atom.

Heres how to make a model atom using school items.

The equipment you'll need for this are-
- Tape
- Paper (Any size)
- Beads ( 3 different colours)
- Blue Tac
- String (30cm preferably, but doesn't matter)
- Any item you can draw with (to draw the electrons)

Method-
- Choose any type of element you want to do from 1-7 on the periodic table
- Get the right amount of beads with different colours representing the Neutrons & Protons)
- Attach the neutrons and proton beads to the blue tac (the right amount to what element you chose)
- Attach ^ that to the string (you can do this anyway, just make sure they stay attached)
- Get your piece of paper, cut two doughnut-shaped  (KNOWN AS THE OUTER SHELL) pieces out, one big and one small enough to fit inside the big one.
- Draw how many electrons you need to in each circle for example, in the small circle of Be-Beryllium would need 2 and 2 in the bigger one.
- Tape your string that is attached to your beads, to the outer shells at the right height so your beads hang in the middle of the smaller shell.
- Cut a square piece of paper out and write your elements chemical symbol, the atomic number and mass number, just like you would see on the periodic table.

What are the 3 main particles in an atom? 
As written above the 3 main particles in an atom are
- Protons
- Neutrons
- Electrons

Electrons are found in the Outer shells also known as orbitals that surround the nucleus of an atom, protons and neutrons are found in the centre of the orbitals (middle of the atom). These 3 particles are so small that the human eye cannot possibly see them, a microscope can also not see the particles.



The element I chose to do was C-Carbon
