6 ANSWERS: Valence Electrons Anions and Cations 9. Predict if ions the following elements will produce Anions or Cations or neither: j. Nitrogen: Anion k. Oxygen: Anion l. Flourine: Anion m. Lithium: Cation n. Potassium: Cation o. Barium: Cation p. Chlorine: Anion q. Argon: Neither r. Carbon: Anion 10. Based on Electronegativity, what is the difference between elements that tend to form Anions and elements that tend to for Cations? Elements that tend to form Anions are more electronegative then elements that tend to for Cations since these elements need to be more electronegative in order to attract extra electrons. 11. From what you know about periodic trends, will transition metals for anions or cations? Explain your answer. These elements for cations since in comparison to the non-metals their electronegativities are low.
7 12. Explain why zinc and cadmium tend to only lose 2 electrons as opposed to other transition metals that may lose more or less? Both elements possess a full d orbital so they preferentially lose only their outermost two s electrons. 13. Predict if ions the following elements will produce Anions or Cations or neither: Beryllium i. Boron: Cation j. Sulfur: Anion k. Iodine: Anion l. Astatine: Anion m. Sodium: Cation n. Hydrogen: Both o. Helium: Neither p. Aluminum: Cation 14. Is there a relationship between atomic size and whether an element will form an anion or a cation? Why or why not? There is a relationship. Since an atom's electronegativity determines if it will be an anion or a cation, and atomic size is a factor in determining an elements electronegativity, there is a relationship between the size of atoms and what type of atom it forms. Small atoms tend to form anions and large atoms tend to form cations. 15. As scientists discover more and more elements, are they more likely to be Cations or Anions? Explain your answer. Since these elements would be larger than previously discovered elements, they would more than likely be cations. 16. Tin can form ions with a +2 and +4 charge. Using your knowledge of electron configurations and orbital stability, explain why these two charges are likely for both tin and lead. Both tin and lead have an outer shell of s2p2. Therefore, they tend to lose either their two p electrons resulting in the +2 charge OR both the outermost p and s electrons resulting in a +4 charge.
