Model Atoms 

 Here is my model of the atom boron (B)

Boron has 5  protons, 6 neutrons, and 5 electrons. 

The protons and neutrons are the particles in the middle. The electrons are the coloured circles on the 2 rings.  The limit of the electrons that can be in the first ring is 2. The limit of the 2 rings is 8 electrons.  So it is written like this 

2,3. Meaning 2 electrons in the first circle and 3 electrons in the second ring.  Electrons always come in pairs. 

The equipment I used to make this are :

Paper 

Tape 

Blue Tac

String 

beads.
