Review A pure substance is when all of the particles are identical. Two main types: Elements Compounds element compound

Mixtures A mixture is when you have different types of particles present. Two main types: Homogeneous Mixture Heterogeneous Mixture Mixture

Mixtures A homogeneous mixture is when particles are evenly distributed throughout. Examples: coffee, laundry detergent, Jello http://examples.yourdictionary.com/examples-of-homogeneous-mixture.html

Mixtures A heterogeneous mixture is when particles are not evenly distributed throughout. Examples: mixed nuts, oil and water, soil http://examples.yourdictionary.com/examples-of-heterogeneous-mixture.html

Atom Video We know electrons move around the nucleus in the electron cloud. https://www.youtube.com/watch?v=lP57gEWcisY But a 3-D model is hard to draw…

Bohr Models Bohr proposed that electrons are in orbits and when “excited” they jump to a higher orbit. When they fall back to the original orbit, they give off light.

Bohr's model: -electrons orbit the nucleus like planets orbit the sun

-Each orbit can hold a specific maximum number of electrons

Bohr’s Model of the Atom Electrons fill orbits closest to the nucleus first. The electrons in the outermost level are known as VALENCE electrons.

Example: Bohr's Model of the Atom Fluorine. : #P = #e- = #N =

Example: Bohr's Model of the Atom Fluorine: #P = atomic # = 9 #e- = #N =

Example: Bohr's Model of the Atom Fluorine: #P = 9 #e- = # P = 9 #N =

Example: Bohr's Model of the Atom Fluorine: #P = 9 #e- = 9 #N = atomic mass - # P = 10

Example: Bohr's Model of the Atom Fluorine: #P = 9 #e- = 9 #N = 10 Draw the nucleus with protons & neutrons 9P 10N

Example: Bohr's Model of the Atom Fluorine: #P = 9 #e- = 9 #N = 10 How many electrons can fit in the first orbit? 9P 10N

Example: Bohr's Model of the Atom Fluorine: #P = 9 #e- = 9 #N = 10 How many electrons can fit in the first orbit? 2 9P 10N

Example: Bohr's Model of the Atom Fluorine: #P = 9 #e- = 9 #N = 10 How many electrons are left? 9P 10N

Example: Bohr's Model of the Atom Fluorine: #P = 9 #e- = 9 #N = 10 How many electrons are left? 7 9P 10N

Example: Bohr's Model of the Atom Fluorine: #P = 9 #e- = 9 #N = 10 How many electrons are left? 7 How many electrons fit in the second orbit? 9P 10N

Example: Bohr's Model of the Atom Fluorine: #P = 9 #e- = 9 #N = 10 How many electrons are left? 7 How many electrons fit in the second orbit? 8 9P 10N

Example: Bohr's Model of the Atom Fluorine: #P = 9 #e- = 9 #N = 10 How many valence electrons are present? 7 9P 10N

Whiteboard Practice Draw each atom on your whiteboard.

Bohr's Model of the Atom Hydrogen 1P 0N How many valence electrons are present?

Bohr's Model of the Atom Boron 5P 6N How many valence electrons are present?

Bohr's Model of the Atom Magnesium 12P 12N How many valence electrons are present?

Valence Electrons Be ready to answer when Miss Kline calls on you. Correct your answers as needed. Go through worksheet together – make sure all correct valance electrons are recorded. ENTIRE worksheet! **Can they do this if they aren’t good with valance electrons?

Valence Activity Each ping pong ball represents an atom. The pipe cleaners represent the valence electrons of the atom. Your job: draw an atom of the element you think your ping pong ball could be, based on the valence electrons. When you finish, raise your hand and Miss Kline will bring you another “atom” to draw. -Pipe cleaners represent valence electrons -Multiple atoms have the SAME # valence electrons -Draw Bohr Model of what you THINK it is -TAKE CARE OF THE PING PONG BALLS Check Bohr model BEFORE giving them the next one Raise hand to get new one – make sure they draw ALL electrons ***COLOR SIGNIFICANT! Finish Bohr Models, explain what happens next

Where do they go? When you think you know where your “atom” goes, bring it up to the periodic table and stick in on. You MAY NOT move anyone else’s “atom” and all atoms must go on to the table. -Put atoms on the periodic table. -You CANNOT move ANYONE’s atom, even if you think they are wrong! Call by row to minimize a million people at board? -REMIND to not move atoms -Go back to seat when you are done Go through one at a time to determine if atom is in correct spot -Randomly moving balls from other spot to correct spot? -Are you seeing a pattern, after the first two rows? -(should be colors by column)

What’s wrong? Which atoms need to move? Which atoms are in the right place? Which are we 100% sure of? Go through this initially together, then ask kid volunteers to change the rest of them (only doing it by color and NOT by number) Need to give the kids more ownership here – kid to fix at front

What do you notice now? How is the periodic table organized? Solidify that it is not only organized by COLOR, but REALLY by valence electron NUMBER!!

Complete the WS Answer each question based on the valence activity. You will turn this in before you leave today. -What do you notice as you move from left to right? -What do you notice as you move down? -
