Read each question carefully and answer to the best of your ability. Show all work for calculations.
1. Which of the following factors has the greatest effect on the strength of Coulombic attraction between two charged particles?
Mass of the particles
Distance between the particles
Temperature of the surroundings
Number of neutrons in the nucleus
2. As the charge of an ion increases, the Coulombic attraction between it and an oppositely charged ion will:
Decrease
Increase
Remain the same
Become repulsive
3. Coulombic attraction describes the attractive force between particles with electrical charges.
4. The force of attraction is directly proportional to the product of the charges and inversely proportional to the square of the between them.
5. Explain how the concept of 'effective nuclear charge' relates to Coulombic attraction within an atom.
6. Shielding effect increases the effective nuclear charge felt by valence electrons.
True
False
