Question 18

3 coulomb’s law conclusions?

Answer 18

1. the potential E of like charges is positive and decreases with distance, as they repel to reach lower potential energy
2. the potential E of unlike charges is negative and becomes more negative as they get closer, as they attract to reach lower potential E
3. the magnitude of the interaction between charged particles increases with the charge increase

Question 19

zeff

Answer 19

effective nuclear charge, the total attraction an e- feels toward the nucleus, with the protons adding / attracting and the other e- subtracting / repelling

Question 20

penetration

Answer 20

a shielded e- coming closer to the nucleus, penetrating the e- cloud of the shielding e-, feeling more attraction, experiencing greater nuclear charge and lowering E
