Given the diagram to the left answer the following questions: Which property of water is represented by the dotted line? Cohesion Hydrogen bonds Adhesion Polarity Because water is __________ , oxygen has a slightly ________ charge and hydrogen has a slightly __________ charge. Properties of H2O: We do

Which of the following pairs of water’s characteristics allows water to travel from the roots of a plant and up its stem? Adhesion and Polarity Cohesion and Hydrogen bonding Adhesion and surface tension Adhesion and hydrogen bonding Anti-gravity ray and dolphins I am carelessly filling my glass with water and I set it on the table. When I look at the glass, I notice that the water bulges above the rim of the glass. Which property of water is responsible for this phenomenon? Properties of H2O: We do

Read the following information and answer questions 5 and 6: It’s no miracle: More than 1,200 species of animals have evolved the ability to walk on water, from tiny insects and spiders to larger animals such as birds, reptiles, and even mammals. Little lizards, known as the Basiliscus, get their food and avoid being eaten by predators by running across the surface of water. Is the lizard floating? What about water allows the lizard to do this? Properties of H2O: We do A double-crested basilisk, dubbed the Jesus lizard, runs across water in Santa Rita, Costa Rica, in 2008. Photograph by Bence Mate, Nature Picture Library/Corbis

Periodic Trends Objective: Explain periodic trends in terms of energy level and distance

Why does the periodic table have such an odd shape? Guiding Question

Warm Up What? (15 min) How? C – Level 1-2 H – Raise hand A diatomic molecule is an element that exists as two atoms that are covalently bonded. Give an example of a diatomic molecule. How would you classify F? Metal Non-metal Metalloid What is the name of the group that F is part of? Name 1 element that has similar chemical properties to F What about F and your answer choice for #4 gives them similar chemical properties? How? C – Level 1-2 H – Raise hand A – Answering 5 questions M – None P – Record responses on left page.

Rules for INM C – No conversation unless helping a peer or minding your manners H – Raise hand A – Take notes M – In seat, no movement P – Writing on guided notes, attention on teacher, head up, answering CFU questions

Periodic trends Trend 3 Trends on the periodic table Definition: A general direction in which something changes Ex: The more I study (cough, cough), the better I do on tests 3 Trends on the periodic table Atomic radius Ionization energy electronegativity Periodic trends

Warning!!! Hydrogen appears in Group 1A, but… There are a lot of instances where it belongs somewhere else When discussing trends, H belongs next to He.

Atomic Radius Smallest Atomic Radius Largest Atomic Radius Definition: The measure of the size of an atom Largest Atomic Radius Radius

C.F.U. Which of the following elements has the largest atomic radius? Ba Ca Al F Arrange the following elements in order of increasing atomic radius O Fr Ga Si

Ionization Energy Highest Ionization Energy Lowest Ionization Energy Definition: The amount of energy needed to remove an electron from an atom Lowest Ionization Energy How much energy will it take to steal this electron?

C.F.U. Which of the following elements has the lowest ionization energy? Ba Ca Al F Arrange the following elements in order of increasing ionization energy B Rb Ca Al

Electro negativity Most Electronegative Least Electronegative Definition: The tendency of an atom to attract more electrons Least Electronegative How badly do I want to take an electron from another element?

Example: Electronegativity For which element would it be easier to get to 8 electrons? The one that already has 7 valence electrons(Chlorine) or the one that only has 1 valence electron (Sodium)?

C.F.U. Which of the following elements has the greatest electronegativity? Ba Ca Al F Arrange the following elements in order of increasing elecrtonegativity B Rb Ca Al Look at your previous answer, what do you notice?

Activity: Graphing Trends How? What? C – None H – Raise hand A – Making visual representations of periodic trends M – None P – Recoding answers on left page, head up, reading and thinking through all questions, discussing with group 20 minutes Follow all instructions and graph two trends

Activity: Independent Practice How? What? C – None H – Raise hand A – Answering questions M – None P – Recoding answers on worksheet, head up, reading and thinking through all questions 10 minutes  Discuss for 5 minutes  Verify & Review

Exit Slip How? What? (5 min) C – No talking H – Raise hand A – Taking exit slip M – In seat P – Completing exit slip without notes and turning in If you finish early, summarize what you learned at the bottom of your notes OR answer today’s guiding question
