Summary:

        There are different parts or groups of the periodic table, such as alkaline metals, alkaline earth metals, transition metals, boron family and more. These are all different because of the amount of electrons in the outer shell and they also are different because of looks, how chemically reactive and more. The numbers of protons is what defines type of atom an atom is and there is typically the same or close to the same amount of protons, neutrons and electrons. The periodic table organizer is Russian Mendeleev and he organized it 25 years before the electrons were discovered.

S&EP:SP1: Asking questions and defining problems:

        I had to find out how many protons neutrons and electrons there were in each kind of element. To do this I found the number of protons by the atomic number and then I found the electrons number because there are the same number of electrons and protons. To find the number of neutrons I took the average atomic mass and I subtracted the number of protons, rounded and found the number of neutrons. We did this for 20 of the different elements that were from hydrogen to calcium.

XCC: Cause and Effect:
        The amount of electrons that you have vs the protons can make it so that the there is a positive or negative or no ion because the charge is unbalanced. When you mix certain elements with things like water and acid it might have a cool chemical reaction because of how chemically reactive a thing is with the other. The reason that the periodic table is formed like it is is because it is from the lowest to highest or the increasing atomic number or number of protons.Another reason that it is formatted like it is is because of if things are metal, non metal etc.
