    General questions about ionic bonds for high school students
  •   Study   Slideshow
  • Is it possible to link 2 atoms from the same chemical element and why?
    No, because it is essential to have very different values of electronegativity.
  •  15
  • True or false: Ionic compounds don't behave as electrical conductors in any situation.
    False, they are conductors in aqueous solution or molten state.
  •  15
  • True or false: Ionic compounds have really high melting points.
    True! They have very strong bonds, for example, NaCl melting point is 801 °C
  •  15
  • Are ionic compounds soluble in water?
    Yes! The hydrogen bonds of water allows ionic molecules to easily dissolve.
  •  15
  • Which ones are ionic bonds: CO, NaCl, CaO, KBr, NO?
    NaCl, CaO, KBr.
  •  15
  • Two non-metalic elements could make a ionic bond?
    No, it is neccesary to have a big electronegativity difference (≥1.5)
  •  15
  • True or false: Lithium is one of the most electronegative elements.
    False, lithium belongs to the IA group in the periodic table, so it's electropositive!

  • The atomic number of Carbon is 6. How many electrons has in its valence shell?
    2. Two unpaired electrons in 2P (2P²)
