DATE A/B DayLEQ: As matter changes states, how doesthe movement and arrangement of theparticles change with it?1. What does the atomic number tell us?2. What does the atomic mass tell us?3. How can we figure out how many neutrons are in aparticular atom?4. How can we tell how many electrons are in anatom?
Energy Levels: hold electrons with the sameamount of energy1st Energy Level 2nd3rdDRAW THIS IN YOUR NOTES!
Drawing Electrons and Energy Levels: HeliumProtons: 2 WHAT NUMBERNeutrons: 2 ROW IS IT IN?! 1Electrons: 2
Drawing Electrons and Energy Levels: BORONProtons: 5 WHAT NUMBERNeutrons: 6 ROW IS IT IN?! 2Electrons: 5
DRAW YOUR OWN!Pick TWO elements and draw models of each of them.You must choose ONE element from the first energylevel and ONE from the second energy level BE SURE TO: LABEL each element you draw DRAW “+” signs in your protons INCLUDE the correct number of protons, neutrons, electrons DRAW electrons in their correct energy level
Summarizer:In 3-5 sentences, EXPLAIN how we can use theperiodic table to determine the structure of anatom.YOUR ANSWER MUST INCLUDE THESE WORDS: PROTON ATOMIC MASS NEUTRON ATOMIC NUMBER ELECTRON ENERGY LEVEL
Today’s LEQ: As matter changes states,how does the movement and arrangement of the particles change with it? By the end of today, you should be able to… 1. Describe the three types of matter 2. Explain how the movement and arrangement of the particles change as the state of matter changes.
Focus Vocabulary:55. Matter56. Solid56. Liquid57. Gas58. Law of Conservation of Matter
Matter: anything that’s made of atoms Picture Particles Density Motion ExampleSOLIDLIQUIDGAS
Matter: anything made of atoms Picture Particles Density Motion Example Usually ParticlesSOLID Tightly packed the most dense locked into place ICE Usually less dense than Particles LooselyLIQUID packed solids, dens er than move Water past each gases other Least Particles Water NotGAS packed at all dense move past each other Vapor
1. Which state of matter is MOST compacted?2. Which state of matter isthe LEAST compacted?3. Which state of matter is the MOST DENSE? Why?4. Which state of matter is the LEAST DENSE? Why?
In your notebook…1. Use the periodic table to list all of the elements that naturally occur as gases2. Use the periodic table to list all the elements that naturally occur as liquids3. Use the periodic table to list 5 elements that naturally occur as solids HOT Q: WHAT DO YOU NOTICE ABOUT THE GASES?
THINK-PAIR-SHARE1. PICK AN ELEMENT2. Use your knowledge of the different states of matter to describe some characteristics of the substance you chose
HOT Q:Which state of matter has a definite volume but NO definite SHAPE?Hint: it can change it’s shape based on the container it is in
• Video – Brainpop (matter of changing states)What causes matter to change states?When matter changes states, do the chemical properties or the atoms change?
HOT Q:When matter changes states, doyou think this is a chemical changeor a physical change? Why?(HINT: Think about chemical vs.mechanical weathering!)
Finish the paragraph…A student is doing an experiment with a substancecalled X. The substance is naturally found in solidform. Once X is heated, it forms a liquid and theparticles 1. [get closer together/spread furtherapart]. Once X is in its liquid form, it is 2.[more/less] dense than its solid form. After Xbecomes a liquid, the student heats it more until itbecomes a 3. [solid/gas]. In this last state ofmatter, the particles 4. [are not packed together atall/are loosely packed together]. In this finalstate, the particles in X 5. [move past each otherfreely/have limited movement].
