Questions and Answers

What is the relationship between the effective nuclear charge and the pull of electrons closer to the nucleus?

  • The larger effective nuclear charge pushes electrons away from the nucleus
  • The larger effective nuclear charge pulls electrons closer to the nucleus (correct)
  • The larger effective nuclear charge has no impact on the position of electrons
  • The larger effective nuclear charge causes electrons to move randomly

What happens to the repulsion force between electrons in a negative ion as the number of electrons increases?

  • The repulsion force between electrons remains constant as the number of electrons increases
  • The repulsion force between electrons decreases as the number of electrons increases
  • The repulsion force between electrons becomes zero as the number of electrons increases
  • The repulsion force between electrons increases as the number of electrons increases (correct)

What effect does the nucleus charge have on the attraction of electrons according to the text?

  • The effect of the nucleus charge on the electrons' attraction decreases (correct)
