What Are We Doing Today?
• Collect Assignment 1• Quiz (find a place away from everyone)• Recycling• Explain APES classes • What is the Difference between:Lewis, Ball & Stick, Bohr Rutherford, Simplified• Isotopes (notes & video)• Metals & Non-Metals Lab
Quiz
• Make sure to sit away from anyone else• You need a pencil or pen• Close your books & notes• Make sure you put your name on the quiz• When you are finished, put your hand up and I
will come and collect your quiz.
Recycling Jobs
How did they go? Any problems?
APES (explained)
Atomic Models…(What is the difference)
a) Ball & Stick b)Lewis Structure c) Rutherford-Bohrd)Simplified
Ball & Stick Model
Draw the ball & stick model for Carbon
Lewis Structure Draw the Lewis model for Carbon
Rutherford-Bohr Model Draw the Ruth-Bohr model for
Carbon
Simplified Model p.28 Draw the Simplified model for
Carbon
ISOTOPES. What are they?
They are different versions of an atom.Isotopes are atoms which have the same atomic
number but different mass numbers. They have the same number of protons but different numbers of neutrons.
• The number of neutrons in an atom can vary within small limits. For example, there are three kinds of carbon atom 12C, 13C and 14C. They all have the same number of protons, but the number of neutrons varies.
PROTONS NEUTRONS MASS NUMBER
CARBON-12 6 6 12
CARBON-13 6 7 13
CARBON-14 6 8 14

- Lab tomorrow (Thursday)- What to do before the lab (questions, prep)- What to do in the lab (safety, partner)- What to do after the lab is over (clean up,
finish questions, hand in)- Lab (prelab + prelab quiz)
Pop Quiz Review
