- 3. Class Notes Power Notes – Topic: ________________________ Atomic Name ________________________________________ Class ________________________________________ Structure Questions/Main Ideas: Period ________________________________________ Date _____________________________________ Notes: • Is made up of tiny particles 1. 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 was 3. How do we know what we discovered throughout know about history from indirect atoms? observations. (without ever seeing an image)….remember the “Whatzit?” 4. How big is the • The diameter is about one atom? hundred-millionth of a centimeter (0.00000001 cm)
- 5. There are three different types of 5. What are the particles; protons, neutrons and basic particles of electrons an atom? They are called subatomic particles • Found in the nucleus (center) 6. What is a of the atom • Positively charged proton? • Mass of 1 amu (atomic mass unit) 7. What is a • Found in the nucleus (center) of the neutron? atom • No charge • Mass of 1 amu
- 6. • Found orbiting outside the 8. What is an nucleus of the atom electron? • Negative charge Draw • Mass of 1/1840 amu this 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 protons 11. Which part of and neutrons) the atom has the • Both subatomic particles have most mass? 1 amu 12. 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 amount are made up of of protons • No two elements have the same amount of atoms, how do we protons know which element • Count the protons in the nucleus and you we 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 (+) and the atoms have? electrons (-),. • Their charges cancel each other out. 15. Are there atoms • Yes, they are called IONS that are charged? • Ions will have more or less electrons than protons • PLASMAS contain IONS
- 9. 16. Periodic Table • Each element box contains all the Connection information for finding the number of subatomic particles • Label the CARBON box using the key on 17. How do you read pg. 196 the Periodic Table box? (pg. 196) • # of Protons 18. The atomic • # of Electrons if the atom is neutral (has number tell you the not charge) number of?
- 10. 19. The atomic mass • Protons added to the number of tells you the number Neutrons of? • In other words: the mass of the nucleus 20. How do you find • Round the atomic mass to the nearest the # of neutrons whole # • Subtract the Atomic Number from the Atomic Mass • Your answer represents the # of neutrons in the most common isotope of an element 21. How do you • Round the atomic mass know which is the • EX: Li 6.9 Most common Isotope = Li 7 • Cu 63.5 Most common Isotope = Cu 64 most common ISOTOPE of an element?
- 11. 22. What is an • Same element with a different # of ISOTOPE? neutrons 23. What is an • Hydrogen 1, 2 & 3 or Protium, Deutirium example of an and Tritium ISOTOPE? • All have 1 proton • Different # of neutrons in the nucleus 24. Illustrate, Label & Color the 3 different forms of Hydrogen (pg. 175) *Clue: Tritium has one electron & 1 proton….how many neutrons?
- 12. 25. How are the • Same # of protons ISOTOPES similar? • Same element Review: Use your notes to help answer the Review questions.
- 13. 1. Power Notes – Due by the end of the period Tomorrow 2. Binder Check #2 - Due Thursday 3. Test #2-1/2 page of notes – Due Thursday
