Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. Define Coulombic attraction in your own words.
2. State Coulomb's Law. What does each variable in the law represent?
3. Which of the following factors would lead to a *decrease* in Coulombic attraction?
Increased nuclear charge
Increased distance between charged particles
Decreased electron shielding
Increased magnitude of charge
4. How does increasing the number of protons in an atom (moving across a period) affect Coulombic attraction for valence electrons?
It decreases attraction.
It increases attraction.
It has no effect.
It first increases, then decreases attraction.
5. The force of attraction between oppositely charged particles is known as .
6. As the distance between two charged particles increases, the Coulombic attraction between them .
7. The shielding effect of inner electrons the effective nuclear charge experienced by valence electrons.
8. A larger nuclear charge generally leads to stronger Coulombic attraction.
True
False
9. Electron shielding increases as you move down a group in the periodic table.
True
False
10. Explain how Coulombic attraction influences the atomic radius and ionization energy trends across a period and down a group in the periodic table.
