Interactive Practice on Periodic Properties

Choose the correct answer.

1. If you have two elements that form an ionic compound,
   • the element with the higher electronegativity is the cation.
   • the element with the lower electronegativity is the cation.
   • either might be true.
2. Which has more electronegativity, N or O?
   • N
   • O
   • both are the same in electronegativity
3. Which has more shielding, N or O?
   • N
   • O
   • both has the same shielding
4. Which is larger, a fluorine atom or a fluorine ion?
   • the fluorine atom
   • the fluorine ion
   • both are the same size
5. Which is larger, a sodium atom or sodium ion?
   • the sodium atom
   • the sodium ion
   • both are the same size
6. Which of the following involves the formation of a negative ion?
   • ionization energy
   • electronegativity
   • electron affinity
   • none of these
7. Which is based on a scale where Fluorine = 4.0?
   • ionization energy
   • electronegativity
   • electron affinity
   • none of these
8. Which has more electronegativity, Na or K?
   • Na
   • K
   • both have the same electronegativity
   • cannot make a judgement without a table
9. Which has more ionization energy, Na or Na+?
   • Na
   • Na+
10. A difference in electronegativity of 0.2 between two elements means that
    • a covalent bond will be formed
    • an ionic bond will be formed
