  5. $ 500 QUESTION Which one of the following has the least valence electrons • Sodium ion • Aluminium atom • Phosphorous ion • Magnesium atom

  6. $ 1000 QUESTION An element E has six electrons in its outer shell. Which of these is most likely to be true? • Forms negative ions • Forms positive ions • Is a nonmetal • Is rather non-reactive

  7. $ 2000 QUESTION Consider 2 particles with the following compositions. Particle X contains 17 protons, 18 neutrons and 18 electrons. Particle Y contains 16 protons, 18 neutrons and 18 electrons. Which best describes the particles? • isotopes • anions • allotropes • cations
