Electron Excitement moving into compounds

Tuesday:
-Periodic Table Quiz, Electron Configuration, Periodic Trends Quiz
-Flame Testing Lab-creating a table of cation vs. color with two unknowns.

Thursday:
-Ground State, Excited State Vocabulary, Ladder Analogy each element has a different energy ladder.
-Atomic Spectra Observations and determining an unknown combination.
-Writing Electron Dot Structures for Atoms and Ions around the room activity.

Monday:
-Review Octet Rule, Electronegativity, and Valence Electrons,
-Review Worksheet and categories for metals and nonmetals.
-Introducing Types of Compounds: Metallic, Ionic, and Covalent Bonds (vocabulary)
-Cups as analogy for electrons and describing the different types of bonds.
-Around the room classifying compounds metallic, ionic or covalent compounds based on names of elements or nature.
-Wednesday quiz on common inner-transition metals.

Wednesday:
Metallic Compounds, Ionic Compounds, Nature and Naming.
Analyzing a food label and determine the properties of the chemicals in those foods.
Follow excel spreadsheet.
Questions: What do you notice about the melting point of ionic vs. covalent compounds?
What do you notice about the boiling point of ionic vs. covalent compounds?
What do you notice about the density of ionic vs. covalent compounds?

Friday:
Start work on naming ionic compounds and determining formulas from charges.
