Intro to the Periodic Table Periodic Trends Graphing

Intro to the Periodic Table Periodic Trends Graphing Activity

• Objective – Today I will be able to: • Explain why different families on the periodic table have similar properties • Evaluation/ Assessment – Informal assessment – Listening to group interactions and discussions as they color and complete the practice sheet – Formal Assessment – Analyzing student responses to the exit ticket and practice worksheet

Lesson Sequence • Engage: Warm – Up • Engage: Coloring the Periodic Table • Explain: Introduction to the periodic table notes • Elaborate: Periodic Table WS – Evaluate: Exit ticket

Warm - Up • What is the most stable family on the periodic table? • Why is this family the most stable? • What families contain the most reactive elements on the periodic table?

Objective • Today I will be able to: – Explain why different families on the periodic table have similar properties

Homework • STEM fair conclusion due Friday, November 14

Agenda • • • Warm – Up Finish Coloring the Periodic Table Introduction to the periodic table notes Periodic Table Worksheet Exit ticket

Finish the Coloring the Periodic Table Activity from Yesterday 10 more minutes to work on the assignment

Reactivity of Metals • Watch the video clip that Mr. Klotz plays and think about these questions: – What families contain the most reactive elements on the periodic table? – Why are they the most reactive elements?

Intro to the Periodic Table Notes

What are the names of the columns and rows on the periodic table?

Families vs. Periods Families = columns • – • Families have similar properties - There are 18 families Periods = horizontal rows - There are 7 periods

There are two ways to number the periodic table:

What is the difference between a metal and a nonmetal?

• • Metals vs. Found to the left of • the “zig-zag” line on the Periodic Table Properties of Metals - Luster: shine • - Malleable: can be hammered into sheets - Ductile: can be drawn into a wire - Good conductors – allow heat and electricity to pass through Nonmetals Non-metals and noble gases are found to the right of the “zig-zag” line Their properties are the opposite of metals

Families on the periodic table have similar properties • Example: Alkali Metals – Soft – Cut with a knife – Highly Reactive

Why do the families of elements have similar properties?

Valence Electrons • Elements in the same family have the same number of valence electrons • Impacts how they bond and why they have similar properties

Metalloids (Semi-Metals) • Most of the elements touching the zig-zag line • B, Si, Ge, As, Sb, Te, and At • They have similar properties of metals and some properties of non-metals

Reading the Periodic Table Practice Complete the WS. Mr. Klotz will collect it as a classwork grade.

Exit Ticket The Mole Refresher! • How many moles of Au are in 2. 24 x 1024 atoms of Au?
