Unit: Matter Focus: Periodic Table Day 17: 9/22/17 Turn in your “Organizing the Elements” worksheet and any late flash cards. Pick up the periodic table on the front lab table. Copy today’s E.Q. onto page 17. Answer the E.Q. on p. 15.

Plan for the Day 1. Review yesterday’s e.q. 2. Discuss homework 3. Various station activities about metals, nonmetals, and metalloids: *Unscramble activity/notes *Shading these 3 categories *Conductivity mini-lab *Metals, nonmetals, metalloids worksheet

Homework: CFA over the periodic table Monday, Oct. 2. Study!!! Flash cards through #28. Bring colored pencils to class next week. Finish one sheet of your element cards. Research the m.p. and b.p. Must be in Celsius. (don’t do properties)

Essential Question– Copy on page 17. What are some properties of metals, nonmetals, and metalloids?

Let’s watch a Brainpop about metals, etc. Brainpop on Metals, etc.

Let’s… Learn about the 3 major groupings on the p.t. Station work- Unscramble activity/notes Conductivity lab Worksheet on metals, nonmetals, metalloids and shading (textbook pp. 244-245)

Properties of the Three Major Categories of Elements 31. Metals 1.Shiny luster 2.Ductile 3.Good conductors of electricity and heat (thermal energy) 4.Malleable 5.Solid @ room temperature (except Mercury-liquid) 6.Melt & boil at high temperature 7.High density Properties of the Three Major Categories of Elements Mercury

Properties of the Three Major Categories of Elements 32. Non-Metals 1.Dull (no luster) 2.Brittle; not malleable or ductile 3.Low melting & boiling points 4.Poor conductors of electricity and heat (insulators) 5.Low density 6.Generally opposite properties to metals 7. Most are gases Carbon

Properties of the Three Major Categories of Elements 33. Metalloids 1.Border the stair step (zigzag) on the right side of the Table 2. Called semi-conductors (can sometimes conduct electricity) 3. Silicon is used in electronic devices 4. Properties of both metals & non-metals 5. Can be shiny or dull 6. Some are malleable and ductile, others are brittle 7. Mostly solid

Let’s watch a Brainpop video about the Periodic Table. https://www.brainpop.com/science/matterandchemistry/periodictableofelements/

Now we’ll take a look at properties of the families (groups) on the P Now we’ll take a look at properties of the families (groups) on the P.T. and fill in our vocab. Sheet. Periodic table groups slide with screenshade.notebook

Group/Family Names & Characteristics Alkali Metals Alkaline-Earth Metals Boron Carbon Nitrogen Oxygen Halogen Noble Gases *Group 1A *Most reactive group of all *Soft *1 valence electron *never uncom-bined in nature *form salts with Gp. 7A *Group 2A *Highly reactive *2 val. Elect. *Group 3A *(Al) is the most common metal in Earth’s crust; *reac-tive *Group 4A *Group 5A *reactive *Group 6A *Group 7A *7 val.el. *poor conduct. *most reactive nonme-tals *Never uncom-bined in nature *form salts with Gp. 1A *Group 8A *8 val. el. *full valence energy level (full outer shell) *non-reactive - inert *non-metals *all gases

Let’s begin shading and discussing the groups (families) of elements on the Periodic Table.

Transition Elements(Metals) All metals Coinage metals; common metals Mostly shiny, ductile, malleable, good conductors, solid (except Mercury) Some are reactive and others are not Iron, copper, gold, nickel, silver

Wrap-up: Use a Venn Diagram to compare and contrast metals and non-metals. See next slide.
