Direct link to Gerry Lennox's post I'm really just checking , Posted 8 years ago. Before we move on, we must discuss how the different types of subatomic particles interact with each other. Frp Insulated Panels, 30 seconds. But the protons and neutrons are still part of the atom, of course, still part of the chemicals, and their interactions are important. We have also distinguish between the possible and common oxidation states of every element. The positive charge on a proton is equal in magnitude to the negative charge on an electron. The third column shows the masses of the three subatomic particles in "atomic mass units." An atomic mass unit ( amu) is defined as one-twelfth of the mass of a carbon-12 atom. Stronitium-84 is composed of 38 protons, 46 neutrons, and 38 electrons. Similarly, adding electrons results in a negative oxidation state.
