Review: What does the atomic # tell you? Warm-up 11/26/13Flash CardOn the Front Write: Valence Electrons On the Back Write: Number of electrons in the outer most shellThe Periodic TableWhere elements come togetherPeriodic Tablean organized list of all known elements that are arranged according to their properties.The 1st 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 TableMendeleevs table was mostly correct, but it is more accurate to organize elements in order of increasing atomic number.

The Modern Periodic Table

Protons = Atomic Number

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

Teach the Teacher: What did you do during the day/after eating thanksgiving (play games, watch football, play football, etc.)

27Example of Messing up Chemical Symbol CO doesnt equal CoCO = Carbon monoxide

Co = Cobalt

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

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

Electrons & The Periodic TableThe 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.Solid, Liquid, or Gas?Electron Shells/OrbitalsThe 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/orbital is added each time.The outer electron shell must be full (usually with 8 e-) to be stable.Teach the Teacher: If you could teach, what grade level would you want to teach and what subject would you like to teach?

Review: How do you find the number of neutrons?Warm-up 12/3/13Flash CardOn the Front Write: Periods On the Back Write: Elements found in the same row (period=sentence)Flash CardOn the Front Write: Groups On the Back Write: Elements in the same column, have similar propertiesElectron Dot DiagramsYou 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 Diagramuses the symbol of the element and dots to represent the valence electrons.

Bohr Model

atom or molecule with missing or extra electronsIons 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

Ions39Teach the Teacher: If you were a bird, what kind of bird would you be? (example: bald eagle, hummingbird, penguin)
