  Dear NSF,                                                                                                   September 8, 1900      Do you ever wonder about how the periodic table was constructed and how people criticize it? Dmitri Mendeleev is heavily criticized for his work from people who don't know all the information. Dmitri shouldn't be criticised and shut down because the way he has organized this system is so great. Also the way he has constructed the system is based off of previous information that has been proven and other scientists have very similar results as him.       The first reason you shouldn't shut him down is because the way he has organized the periodic table is so brilliant. Everything in his periodic table link up. The mass numbers link up because they are put from least to greatest. The energy levels and chemical properties also link up because each family has similar chemical properties. For example, all of the alkaline metals (family 1) have

Summary: Link This week in science we learned about Dmitiri Mendeleev (the creator of the periodic table) and the periodic table. We learned that one of the biggest reasons Dmitri Mendeleev made the periodic table was because he wanted to put into a science textbook and by making it into a table it would fit in the textbook. We learned that for the periodic table instead of saying row and column we say period (for row) and family (for column). We also learned about a pattern that the periodic table has which is that with each period there is one more energy level for electrons. Also that elements in the same family have similar chemical reactions. We also learned about what the periodic table consists of and the families within it. The periodic table consists of metalloids, metals, and nonmetals. The families are the Alkali Metals (Family 1), Alkaline Earth Metals (Family 2) Transition Metals (families in the middle), Boron Family (Family 3), Carbon Family (Family 4), Nitrogen F

Summary: Link      This week in science we learned about elements and ions through taking notes and completing an assignment. We learned about the components of how each element looks on the periodic table, the components are the element name, the element symbol, the atomic number, and the average atomic mass. We also learned what ions are and what types of ions there are. Ions are atoms that have lost or gained electrons. There are two types of ions, a cation and an anion. Cations are ions that have lost electrons which also means they have a positive charge. If you were to show that something is a cation you would have in superscript after you write the element an addition symbol with a number next to it representing how manh electrons were lost. This shows that they have lost electrons which means they have a positive charge. Anions are ions that have gained electrons which means they have a negative charge. You would write this in your superscript which is after you write t

      Dear King Arthur,                                                                                         9/6/17         I have done some research and I believe I have found your crown. Your pure gold crown was the crown delivered by Gawain. I found this through finding the mass and volume of each crown. We know that golds density is 19.3 g/cm3. We also know that in order to find density we must do mass divided by volume. Density is how much stuff we have in a given space and how close somethings atoms are together. So I have done mass divided by volume for each crown. The crown with the same density as gold (19.3 g/cm3 ) is your crown. I know this because your crown is made of pure gold and that would mean that your crown has the same density as gold.       The crown delivered by Lancelot has a mass of 1890 grams and a volume of 180 cm3 and 1890 divided by 180 is 10.8 g/cm3. Which means it is not the correct crown because it doesn't have the same density as gold the mat

Link Summary This week in science we learned about matter and atoms through various activities like taking notes, a gizmo, and completing a doc. I learned that most of the weight of an atom is in the nucleus. What makes up the nucleus is neutrons and protons and the electrons are left on the outside. Also that in the space between the electrons and the nucleus their is absolutely nothing there to fill that space. I also learned what density is, it is how close an objects atoms are together and how much stuff we have in a given space. Or as most people put it mass divided by volume equals density. llAnother thing I learned was a good definition for molecules, compounds and elements. A molecule is when 2 or more atoms are chemically bonded, a compound is when two different atoms are chemically bonded, and an element is when one pure atom makes up a substance. Also that all compounds are molecules but not all molecules are compounds. S&EP 4-Analyzing and Interpreting Data I
