Protons, Neutrons, Electrons

I learned how to identity each element in the periodic table and how to fin the mass number of each when they fo not give it to you. I also learned that the atomic number, neutrons and the protons are all equal. All elements have a chemical symbol, number of protons, number of neutrons, number of electrons, mass number, and a atomic weight. Mass number is the number of protons plus neutrons together.

Periodic Table

What i leanrned was very interesting about the periodic table. Well first some of the patterns that my group found out when you are reading from up to down the atomic mass increases. When you are reading from left to right the electron count increases. Lastly when you read from up to down and down to up you will see the different color groups. Also my group and I learned about the non-metals and metals and ther different characteristics that the two groups have.
