Read each question carefully and answer to the best of your ability. Show all work for calculations.
1. Which of the following factors would lead to a *decrease* in Coulombic attraction between two charged particles?
Increasing the magnitude of the charges
Decreasing the distance between the particles
Increasing the distance between the particles
Increasing the number of protons in the nucleus
2. Which element would experience the *strongest* Coulombic attraction between its nucleus and its outermost valence electron?
Lithium (Li)
Fluorine (F)
Potassium (K)
Chlorine (Cl)
3. Coulombic attraction describes the attractive force between objects of charges.
4. According to Coulomb's Law, the force of attraction is directly proportional to the product of the and inversely proportional to the square of the between them.
5. The shielding effect refers to the reduction of the effective nuclear charge on valence electrons due to the presence of electrons.
6. Explain how increasing the number of protons in an atom's nucleus affects the Coulombic attraction experienced by its valence electrons, assuming the distance remains relatively constant.
7. As you move down a group in the periodic table, the Coulombic attraction between the nucleus and the valence electrons generally increases.
True
False
8. The effective nuclear charge (Zeff) experienced by an electron is always equal to the actual nuclear charge (Z).
True
False
9. Discuss the periodic trends of atomic radius and ionization energy in relation to Coulombic attraction and effective nuclear charge. Provide specific examples to illustrate your points.
