1.   Teacher the Teacher: What is your least favorite food?  Review: What is the independent variable? Warm-up 10/23/12

2. Where elements come together

3.   Periodic Table —an organized list of all known elements that are arranged according to their properties.  The 1 st person to organize elements was Dmitri Mendeleev in the 1800s.  Mendeleev organized the elements by their atomic mass and left spaces for unknown elements. The Periodic Table

4.   Mendeleev’s table was mostly correct, but it is more accurate to organize elements in order of increasing atomic number. Mendeleev’s table The Modern Periodic Table

5.   Protons = Atomic Number  Atoms get their identity and properties due to the number of protons they have  change the #p+ change the element  Electrons = Number of protons  For neutral atoms, ions are different  Neutrons = Atomic Mass – Atomic Number  Atoms of the same element can have different masses. These are called isotopes. The difference in mass is due to more or less neutrons

6. Atoms: by the NUMBERS the element song

7.   Teach the Teacher: If you had to be a teacher what subject would you want to teach? What subject do you think would be the hardest to teach?  Review: Is CO2 a compound or element, or mixture? Warm-up 10/24/12

14.   Teach the Teacher: What is the best outdoor winter activity?  Review: What is the group that you do nothing too? Warm-up 10/25/12

15.  Flash Card On the Front Write:  Atomic Number On the Back Write:  Top number, tells the number of protons and electrons

16. Chemical Symbols (Scientist Texting)  Abbreviations for chemicals  Punctuation is KEY  Capital Letters big, little letters small  Spacing  Elements  ALWAYS Start with a capital letter  Symbols can be 1,2 or 3 letters  First letter is capitalized and 2 nd & 3 rd are lowercase

17. Example of Messing up Chemical Symbol  CO doesn’t equal Co  CO = Carbon monoxide Co = Cobalt

18.   Periods —horizontal rows of elements on the periodic table.  Periods are numbered 1-7  Elements increase by one proton as you move from left to right across a period. Periods

19.  Groups  Groups (or families) —vertical columns on the periodic table.  They are numbered 1-18.  Elements in each group have similar properties.

20.  Electrons & The Periodic Table  The periodic table organizes elements based on where their electrons are located.  Electrons (e - )—are located in different energy levels around the nucleus.  Elements in the same group have electrons arranged similarly which gives them similar properties.

21.  Solid, Liquid, or Gas?

22.  Electron Shells  The number of energy levels or electron shells is determined by the period number.  Period 1: 1 electron shell and can hold 2 e -  Period 2: 2 electron shells & can hold 8 e -  Period 3: 3 electron shells & can hold 16 e -  As you move down the periodic table, 1 electron shell is added each time.  The outer electron shell must be full (usually with 8 e - ) to be stable.

23.   Teach the teacher questions: If you could get a gift card to any store in the mall, what store would it be?  Review: List as many elements as you can think of (you can use resources). Warm-Up 10/26/12

24.  Electron Dot Diagrams  You can show the number of electrons in the outermost electron shell by using an electron dot diagram.  Dot diagrams use valence electrons which are the electrons in the outer electron shell.  Electron Dot Diagram —uses the symbol of the element and dots to represent the valence electrons.

25.   atom or molecule with missing or extra electrons  Ions are charged particles (positive or negative)  charge = #protons - #electrons  charge given as a trailing superscript  positive ions are cations X +  negative ions are anions X – Ions
