Wouldn't it be awesome if our periodic table looked like it does in the top corners? Well it could be if it fit in our textbooks. The only reason that we had the plain old boring square one we have today is because teachers needed to be able to print it in a text book. Well we're speaking of the periodic table. Let's talk about it's history. The periodic table did not always look like it does today, actually there didn't use to be one. Dmitri Mendeleev invented the periodic table. Only because he needed a way to organize all the elements so that it made sense. So he started organizing them by patterns. Then he realized that some of the elements that reacted the same way actually were a lot like each other. But some of the other elements reacted completely different but had things in common. "You look like your family, but not like your neighbor" is a good saying to describe it. While this might already be confusing but what use if the periodic table if you don't know how to read it? Reading the periodic table is actually easier than you think. The first column that has Hydrogen, Lithium, and Potassium,(H, Li & K) All have one atom in the outer shell of electrons. The second column containing Beryllium, Magnesium, & Calcium, (Be, Mg, & Ca) all have two valence electrons. The third Column that contains Boron and Aluminum (B & Al) all have 3 valence electrons. Can you guess the fourth column? Let's see they have four valence electrons. The fifth column has five valence electron. The sixth column has six valence electrons.The seventh column has seven valence electrons. The eighth column has eight valence electrons. Then how you find out the Period is how many layers of electrons does the atom have. Then that number determines the row or period.

SP2 Using Models

We used models when we were studying the periodic table because we used the periodic table which is a model to help us figure out how to read it. We also used the model of the atom to help find out which element was where on the periodic table. We also used the model of the periodic table to show how all of the elements were organized and why. Also what they had in common.

XCC Energy & Matter

Energy and matter take part in the systems that we are studying in class because the system of the periodic table has gases and metals which are two different types of matter. One is a solid and one is a gas. Energy takes part in the system because the elements all conduct different amounts of energy. These are just two examples of how energy and matter take part in the system of the periodic table.

This week I think that I was a learner. I think that I was the learner this week because I was always wanting to know more and I was very interested in the periodic table. I really wanted to know more and I find chemistry very intriguing and it pulls me in to learn more.
