Today Finished our discussion about the history of the atom. We learned about subatomic particle called quarks. There are 6 type of quark but the type that make up protons and neutrons are up and down quarks. Electrons are not made of quarks. (See image 1 below.)
We then started to fill in our atom foldable. Here we are putting all of our knowledge about the atom onto an easy to use format.
We read pp. 321-322
Please note that the proton has a (+) positive charge
and the neutron has a (0) neutral charge
