Energy levels and Exploring the Periodic Table! - Weekly Blog #18

https://www.learner.org/interactives/periodic/elementary2.html

Summary

This week in science, we studied the energy levels of an atom. The energy levels in an atom show how many electrons there are in an atom, and which level they are in. We also identified and explored the different elements of the periodic table, including how it is sorted. This gave me a much deeper understanding of different elements and how much sense it makes in the way they are sorted. The periodic table was created by a man named Dmitri Mendeleev. As the years went by, others added to his ideas to created the modern periodic table that we know today. Now to explain how the periodic table is sorted. The periodic table is sorted in increasing atomic energy levels. There are periods (rows) and family's (columns) in the periodic table. This is the way the periodic table is arranged in. These are the things I learned this week.


S&EP - Constructing explanations and designing solutions

I constructed an explanation of how the periodic table is sorted when I analyzed the data of each element and how they are sorted on the table. This was done through learning about the different families, such as the alkali, alkali earth metals, transition metals, boron, carbon, nitrogen, oxygen, halogen, rare earth metals, and noble gasses. All of these family's have distinct features and properties. I was also able to identify that all metals are at the left, nonmetals at the right, and metalloids are the 7 elements boarding the metals. This is how I constructed an explanation of how the periodic table is sorted this week.

XCC - Patterns

I learned about the constant re-occurring patterns of the periodic table, as well as a similar pattern that can be found in an atoms energy levels. this can be identified through the similar features of period . and as you go down a period there is a gradual change in chemical properties, but if you looked at a family of elements, you will notice that elements in a group have similar chemical and physical properties. This is due to the pattern of having the same amount of outer electrons. This is how I identified patterns this week.
