Read each question carefully and answer to the best of your ability. Show all work for calculations.
1. Which of the following best describes Coulombic attraction?
The repulsion between like-charged particles.
The attraction between opposite-charged particles.
The force that holds a nucleus together.
The force of gravity between two atoms.
2. What happens to the strength of Coulombic attraction as the distance between two charged particles increases?
It increases.
It decreases.
It remains the same.
It first increases, then decreases.
3. The magnitude of Coulombic attraction is directly proportional to the of the charges and inversely proportional to the square of the between them.
4. In an atom, electrons are attracted to the due to Coulombic forces.
5. Explain how the number of protons in an atom affects the strength of Coulombic attraction experienced by its outermost electrons.
