Transcript

  • 1. You Will Need:1)Pencil, Colored Pencils2)Power Notes – Atomic Structure – Book shelf 3 pages 6 sides- Please Staple.
  • 2. Reminders :1.Binder Check #2 – Due at the beginning of class on Thur. 1.Table of Contents on-line 2.Edit out my notes 3.Number your pages starting with Log #22. ½ page of notes for Test #2 – Thur- Computer, Fri-Written portion Front side only – Done by hand
  • 3. Class Notes Power Notes –Topic: ________________________ Atomic Name ________________________________________ Class ________________________________________ StructureQuestions/Main Ideas: Period ________________________________________ Date _____________________________________ Notes: • Is made up of tiny particles1. All Matter called atoms. 2. What are • Smallest particle into which Atoms? an element can be divided and still keep its properties. • EX: one atom of gold still has all the properties of gold….but if you split the atom it is no longer gold.
  • 4. • Most of what we know was3. How do weknow what we discovered throughoutknow about history from indirectatoms? observations. (without ever seeing an image)….remember the “Whatzit?”4. How big is the • The diameter is about oneatom? hundred-millionth of a centimeter (0.00000001 cm)
  • 5. There are three different types of5. What are the particles; protons, neutrons andbasic particles of electronsan atom? They are called subatomic particles • Found in the nucleus (center)6. What is a of the atom • Positively chargedproton? • Mass of 1 amu (atomic mass unit)7. What is a • Found in the nucleus (center) of theneutron? atom • No charge • Mass of 1 amu
  • 6. • Found orbiting outside the 8. What is an nucleus of the atom electron? • Negative chargeDraw • Mass of 1/1840 amuthis pic • This particle determines how the element will bond • This particle also determines the charge of the atom • Positive 9. What charge • Only protons (+) and neutrons does the nucleus (no charge) in the nucleus have? Why? • No other particles to cancel out the + particles in this space
  • 7. 10. What part of • The electron cloud the atom take up • EX: If the center of an atom was the size of a bee, the atom would be as the most space? big as a football stadium (volume) • The nucleus (contains protons11. Which part of and neutrons)the atom has the • Both subatomic particles havemost mass? 1 amu12. What does • Pg. 174 in your text. • Label: proton, neutron, electron &a model of the nucleus.atom look like? • Label their charges. • Color each particle a different color
  • 8. 13. If all elements • Each element has their own unique amountare made up of of protons • No two elements have the same amount ofatoms, how do we protonsknow which element • Count the protons in the nucleus and youwe are looking at? can identify what element you are looking at • Atoms found on the Periodic Table are electronically neutral.14. What charge do • They have the same # of protons (+) andthe atoms have? electrons (-),. • Their charges cancel each other out.15. Are there atoms • Yes, they are called IONSthat are charged? • Ions will have more or less electrons than protons • PLASMAS contain IONS
  • 9. 16. Periodic Table • Each element box contains all theConnection information for finding the number of subatomic particles • Label the CARBON box using the key on17. How do you read pg. 196the Periodic Tablebox? (pg. 196) • # of Protons18. The atomic • # of Electrons if the atom is neutral (hasnumber tell you the not charge)number of?
  • 10. 19. The atomic mass • Protons added to the number oftells you the number Neutronsof? • In other words: the mass of the nucleus20. How do you find • Round the atomic mass to the nearestthe # of neutrons whole # • Subtract the Atomic Number from the Atomic Mass • Your answer represents the # of neutrons in the most common isotope of an element21. How do you • Round the atomic massknow which is the • EX: Li 6.9 Most common Isotope = Li 7 • Cu 63.5 Most common Isotope = Cu 64most commonISOTOPE of anelement?
  • 11. 22. What is an • Same element with a different # ofISOTOPE? neutrons23. What is an • Hydrogen 1, 2 & 3 or Protium, Deutiriumexample of an and TritiumISOTOPE? • All have 1 proton • Different # of neutrons in the nucleus24. Illustrate, Label &Color the 3 differentforms of Hydrogen(pg. 175)*Clue: Tritium hasone electron & 1proton….how manyneutrons?
  • 12. 25. How are the • Same # of protonsISOTOPES similar? • Same element Review: Use your notes to help answer the Review questions.
  • 13. 1. Power Notes – Due by the end of the period Tomorrow2. Binder Check #2 - Due Thursday3. Test #2-1/2 page of notes – Due Thursday
