Question 1

What is the name of the force that holds two atoms together?

Chemical Bond

Question 2 The chemical bond that holds two or more nonmetals together is called what?

Covalent Bond

Forming Chemical Bonds

• The force that holds two atoms together is called a chemical bond.

• There are three types of bonds:• Ionic bonds (Metal/Nonmetal)• Covalent bonds(Nonmetal/Nonmetal)• Metallic bonds(Metal/Metal)

The Formation and Nature of Ionic Bonds• Cations are atoms with a positive charge.• Anions are atoms with a negative charge.• The electrostatic force holds ions of opposite

charge together, forming an ionic bond.

Question 3 • Fill in the missing blanks using vocabulary words.

Ionically bonded substances include metals and _________. They are held by _______________ forces. They form salts but also form crystal ___________ structures. When dissolved in water, they form an aqueous solution or mixture that conducts ________________.

Fill in the Graphic Organizer

Covalent Ionic Metallic

Now fill in what is missing, put stars next to them so you know that’s what you need to remember

Ionic BondsCharacteristics of ionic bonds:

Formed between metals and nonmetalsHigh melting point and boiling point.Able to conduct electricity when dissolved in water.Unable to conduct electricity in the solid phase.The strength of the bond depends on the charges, and

distance between ionsIonic bonds form a lattice structure

Covalent Bonds• Characteristics of covalent bonds:• Formed between nonmetal pairs• Electrons are shared between atoms• Lower melting points, Lower Boiling Points• Do not conduct electricity• Brittle solids

Metallic• Properties of metallic bonds:• Delocalized electrons• High electrical conductivity• High luster (shiny)• Remember that transitional metals have a varying

number of valence electrons.

Predict if the following bonds are ionic or covalent:

a) C-Nb) N-Oc) Na-Fd) Mg-Se) C-Hf) Ca-F

Predict if the following bonds are ionic or covalent:

a) C-N - Covalent b) N-O - Covalentc) Na-F -- Ionic d) Mg-S - Ionice) C-H - Covalent f) Ca-F - Ionic

What is an alloy?• An alloy is a mixture of two or more metals.

Names and Formulas for Ionic Compounds• The simplest ratio of the ions represented in an

ionic compound is called a formula unit.

The oxidation number of an ion can be determined with the aid of the periodic table.

+1

+2 -1-2-3+4+3

0For transitional metals below, charges vary so when naming ionic compounds with these elements, put the charge in parenthesis after the metal.

Example

Copper can have a +2 or +3 charge so to know which it is you put parenthesis next to the transitional metal.

Cu (II) means copper with a positive 2 charge Cu2+

Cu (III) means copper with a positive 3 charge Cu3+

Honors: Think- Pair-Share•Why do some elements have a positive oxidation number and some other elements have a negative oxidation number?

Hint #1: Electronegativity Hint #2: Periodic Table

Predict the oxidation number of the following elements:a) Alb) Mgc) Sid) Oe) Cl

Predict the oxidation number of the following elements:a) Al +3b) Mg +2c) Si +4d) O -2e) Cl -1

Nomenclature for Ionic Formula Units

There are over 50 million substances!

We CANNOT have unique names for all these substances, that would be too much!

That is why we have naming rules.

Nomenclature• Steps for writing ionic formulas:

1. Determine the symbol and oxidation number of the elements

2. If the charges are not the same, subscripts must be added to achieve equal number of positive and negative ions.

3. Criss-cross, ignore charge, write formula4. Metals always first, then nonmetal 5. NO prefixes needed. 6. Ionic formulas end in -ide

Show on Dry Erase:1. Example 1: calcium chloride2. Example 2: Potassium oxide

ExamplesWrite the formula of the following ionic compounds:• Magnesium chloride• Aluminum oxide• Iron (III) chloride• Chromium (III) oxide

You try first, then confirm with partners. Write the formula of the following ionic compounds:

a) Cesium nitrideb) Barium sulfidec) Calcium oxided) Aluminum fluoridee) Sodium oxide

What if the charges are the same, then just ignore charges, and write the formula, no need for criss- crossing!

For HW, you will be asked to on Page 30L:

Phase 3 Get into your groups Finish Trifold or Poster or Presentation Your poster shouldn’t be wordy, should be

something to refer to while you and your group members present.

Gchem:①Work on Review Project ②Study for finals

An effective presentation includes As FEW of words as possible Pictures because they says a thousand words

You can put notes below the PowerPoint and you can refrence these during the presentation or use flashcards during a presentation to quickly reference to.

Overall Task Hook your audience You are PURSUADING us that your source is the best. You are trying to sell this source to your peers

Effective Speakers

1. Confident Voice2. Look at all individuals in the audience3. Dont read off their notes/PowerPoint4. Lots of practice before a speech

Confident Voice• Be confident of yourself• You are the expert!• We are all on the same team. • Some may want to outline what they are going to say in order to

help them practice

Practice• No one does great at anything on the first try• You need to practice what you are going to say so

that you are prepared; this is why you are presenting multiple times versus traditional front of the class presentations

Criteria for Success1. Run through your presentation at least once with your group (20

min) 2. First 4 groups will set up their stations. The next four 4 groups

will complete the Presentation Feedback GoogleDoc Form for each group. You can find this on the homepage on this website: mrnarez2014.wordpress.com

3. 7 minutes per station, rotate sound of the bell. 4. Swap between presenters and audience, repeat.

Socratic Seminar Out Circle Norms

When your partner speaks in the inner circle, you will use the discussion board found in mrnarez2014.wordpress.com

①1. Summarize what your partner said (To summarize what Edgar said...)

②2. Clarify their answer if they were unclear (What I think Kimberly was trying to say was...)

③3. Ask them a probing question, question their rationale, their evidence, make them think more in depth (Isaac, I think the quote that you used during the seminar about hydroelectric energy meeting the energy demands of our country was misunderstood, what I think the quote meant was...)

During the debrief (5 min coaching session), you will assess how your peer did during the discussion. You will use the criteria for success checklist to given feedback.

You will complete this at the end of class.

Incorrectly grading your peer will lead to a deduction of your own grade.

Naming Organic Compounds

Organic Compounds containing carbon and hydrogens • Hydrocarbons are named by counting the number

of carbon atoms:

C1 – meth C6 – hex

C2 – eth C7 – hept

C3 – prop C8 – oct

C4 – but C9 – non

C5 – pent C10 – dec

3 types of hydrocarbons• The ending depends on the type of bond formed:• Single bond: -ane (Alkanes)• Double bond: -ene (Alkenes)• Triple bond: -yne (Alkynes)

Is it a ring or a chain?• The number of carbon atoms in a compound is

calculated by the formulas:

• CXH2X+2 for chains

• CXH2X for rings

ExamplesWrite the formula for each of the following: a) methaneb) butanec) cyclopropaned) C5H12

e) C6H14
