AP Chemistry – Class 40

Dates

• Periods E/F – Tuesday, November 20th

BIG QUESTION: how are the electrons in an atom identified?

ACTIVITY

• write down your identifying information
• address, phone, school, height
• Could you be found based solely on this information?

INFORMATION

• 4 Quantum Numbers (n, L, mL, ms)
• Each has allowed values
• n = integers starting @ zero
• L = integers from 0 to (n-1)
• mL = integers between +L and -L
• ms = +1/2 or -1/2

ACTIVITY

• write the 4 quantum numbers for electrons that have n = 0 through n = 3
• what do you notice about the combinations?

TEST RETAKE

• Wednesday, November 28th @ 7:00
• 45 minutes
• 3 Questions – same topics
• I will average the scores
