Questions and Answers

Why are the first elements of the second-period elements significantly different from their congeners?

  • The extraordinarily small size (correct)
  • The larger charge
  • The unavailability of the d orbitals
  • The greater probability of pi bonds formation

    • What effect does the extraordinarily small size have on the second-period elements?

  • Larger charge and decreased covalent character
  • Smaller electron affinities and increased covalent character (correct)
  • Greater probability of sigma bonds formation
  • Higher electronegativity and reduced overlap of electron clouds

    • Why isn't Fluorine the most accepting of electrons among Group 7 elements?

  • It has a lower charge density than chlorine
  • It is a very small atom with strong repulsion force (correct)
  • It has a higher electron affinity than chlorine
  • It has a higher electronegativity than chlorine
