Questions

  1. 1.

    According to Coulomb's law, which statement best explains why the first ionization energy generally increases from left to right across a period of the periodic table?

    • A) The principal quantum number increases, significantly increasing the average distance between the nucleus and the valence electrons.
    • B) The increase in electron-electron shielding causes the net positive charge felt by valence electrons to decrease across the period.
    • C) Additional inner-shell core electrons are added, causing electrostatic repulsive forces to overwhelm the nuclear pull.
    • D) The effective nuclear charge increases while the valence electrons occupy the same principal energy level, resulting in a stronger electrostatic attraction.
