2. Click on the word pages on the top of your page in the blue background.
3. Click add and create a page named Periodic Table of Elements.
4. Post these things on your Periodic Table of Elements page-
*A Picture of the Periodic Table of Elements.
*Explain what periods are and what they tell you about those elements in each period.
*Explain what groups or families are and what they tell you about those elements in each period.
*Explain how elements are classified in the Periodic Table as:
-Valence Electrons (how do you know the # of valence electrons)
-Metals (Where are metals found?)
-Nonmetals (Where are nonmetals found?)
-Metalloids (Where are nonmetals found?)
-Atomic Number (What does the atomic # tell us about the element and how is it arranged on the periodic table?)
-Atomic Mass (Where is the atomic mass found and what does it tell us about the element?)
*Explain how you know if elements are highly reactive or not.
*List the properties of metals, nonmetals, and metalloids using physical properties such as luster conductivity, and malleability.

On the periodic table,each period,the up and down columns, tells you how many energy levels,or levels that electrons float around on, the different elements have.The groups or families,the side to side columns, tell you how any valence electron,or electrons on the outer most energy level,an element has.On the periodic table the elements are mainly classified by the atomic number, the number of protons the atom has.As previously stated,the number of valence electrons can be determined by the number of the period the element's in.To locate the metals look to the middle of the table from group 21 to group 30.Nonmetals however are found to the right of the "stairs" in the right hand corner.Metalloids,which contain the characteristics of metals and nonmetals, are found surrounding the "stairs" which include:B,Si,Ge,As,Sb,Te,and Po.The atomic numbers tell you how many protons are in the atom.Atomic mass,which is the tiny numbers under the element's symbol,tell you how much the element weighs.The closer you get to the middle of the table,the less reactive the elements get.groups 1 and17 are the most reactive due to them having to do the least amount of work to become stable.As for physical attributes,met els are good at conducting electricity,unlike nonmetals.Metalloids however conduct electricity too due to them possessing the properties of nonmetals and metals.
