Thursday 9 November

• Lewin Yu

Friday 10 November (briefly done - volleyball at state)

• valence shell
• can gain or lose e^-s
• What chemistry is all about
• Factors influencing periodic trends
• (1) filled and half-filled sublevels
• (2) distance between nucleus and valence e^-s
• (3) e- shielding
• (4) internal charges
• (1) filled and half-filled sublevels
• special stability
• predicted and actual electron configurations
• Cr, Mo and Cu, Ag
• (2) number of energy levels
• electromagnetic attraction decreases with distance
• (3) number of electrons
• they shield the positive nucleus
• (4) ratio of charge to number of energy levels
• north pole / south pole magnetic attraction
• increasing magnets increases attraction
