Introduction to Chemistry Do Now: Place your Binder and Composition Notebook on your desk. CLEAR ALL OTHER ITEMS OFF OF YOUR DESK.

Binder organization!! Label your dividers with the following titles and in the following order: Do Now Trackers Assessments Notes Study Guides Resources

Quiz Tracking There are no constraints on the human mind, no walls around the human spirit, no barriers to our progress except those we ourselves erect. Ronald Reagan What is progress? How do you know when progress is being made?

Our Class Progress Raising that bar is a CLASS EFFORT! Every person in this room contributes to our progress Understanding your progress will increase OUR progress. academic trackers Track your quiz and then REFLECT on your progress by answering the questions in the graph This should be an INDEPENDENT activity All students should be at a noise level 0 All questions should be directed to the teacher by raising your hand.

Celebrate Your Successes!! Focus your attention to our data board. Our class goal: all students score over an 80% on all quizzes and tests. If you made an 80% or above on our observations and inferences quiz please come forward to receive your sticker If you made an 80% or above on our characteristics of life quiz please come forward to receive your sticker. When you are finished tracking and placing stickers start the class warm up in the Do Now section of your binder.

Warm Up What part of the atom is positive and found in the nucleus Warm Up What part of the atom is positive and found in the nucleus?   (this should be review from middle school)

Atoms, Formulas, and Reactions Notes Atoms, Formulas, and Reactions

I. The Basics About Atoms A. All matter is made up of atoms. 1. Atoms are microscopic particles that join together to create everything. 2. There are different types of atoms. Each different type is called an element. B. A compound is made up of more than one element.

Flashcards!!! Vocabulary we have learned so far today: Atom: Microscopic particle made of electrons, protons and neutrons Element: A specific type of atom Molecule: 2 or more atoms bonded together Compound: A molecule made up of more than 1 element

I. Writing Formulas A. Formulas are used to represent elements and compounds in writing. 1. Symbols are used to represent individual elements. a. C=carbon (all living organisms contain carbon) b. N=nitrogen c. O=oxygen d. H=hydrogen 2. Subscripts are used to tell us how many atoms of a particular element there are. For example, in CO2 it tells us there are 2 oxygen atoms and 1 carbon atom.

Whiteboard Practice For each state whether it is a compound or element, what atoms each symbol is, and how many of each element there are. H20 O C6H12O6 NO3 C N2

Do Now Answer the following questions about this molecule: C12H22O11 Compound or element? What elements do C, H, and O, represent How many atoms total are in this molecule.

II. Bonding First we’re going to model ionic bonds. Throw a ball from one person to another. The ball is being transferred. Second we’re going to model covalent bonds Now, both hold onto the ball together. The ball is being shared. Which bond do you think is stronger?

II. Bonding A. When atoms join together it is called bonding. 1. Covalent bonding is when atoms share electrons. Strong bonds.

II. Bonding 2. Ionic bonding is when electrons are gained or lost. Weaker bonds. a. The negative and and positive charges formed attract to each other

Flashcards More Learning!! Yay!! Ionic Bonding: electron is given from one atom to another. (weak bond) Covalent Bonding: atoms share electrons (strong bond)

III. Chemical Reactions Example Reaction: NaCl + AgNO3 --> NaNO3 + AgCl A reaction is a process that leads from one set of substances to a new set. 1. Atoms are not lost or gained in a reaction. 2. The substances that you start with are called the reactants. The substances you end up with are called the products. 3. The arrow represents the direction of the reaction.

Whiteboard Practice Practice Reaction: SO3 + H2O  H2SO4 What is/are the reactant(s)? What is/are the product(s)? Does the number of oxygen atoms change in the reaction? Does the number of compounds change in the reaction? Which elements in the reaction equation are commonly found in living organisms? For each compound in the equation label the elements and the number of each element.

Do now: Answer the following questions in your notes: Students will answer the following questions: What is the difference between an element and a compound? What is the difference between ionic bonds and covalent bonds? In a reaction equation you start with the _______ and end up with the _______. What happens to the number of atoms during a reaction? What is a reaction? What does an arrow represent in a reaction equation?

Extend: Honors Biology Use the model set to make 2 of the following molecules. 2. In a certain reaction, two of these molecules combine. Show how this happens and draw it in your notebook. (Hint: only 1 H2O is lost)
