1 Look at a periodic table to answer the following questions: 1. What is the name of group 1? 2. What is the name of group 2? 3. What is the name of group 17? 4. What is the name of group 18? 5. What is the name for the d block? 6. What is the name for the s & p block? 7. What is the name for the 2 periods at the bottom of the periodic table? Answer the following questions with these terms: Noble gases Halogens Alkali metals Transition metals Alkaline-earth metals 8. The have a single electron in the highest energy level? 9. The achieve the electron configurations of noble gases by losing two electrons. 10. The vary in the number of electrons in the highest energy level. 11. The achieve the electron configurations of noble gases by gaining one electron. 12. The have full s and p orbitals in the highest occupied energy levels. 13. The are stable and unreactive. 14. The are highly reactive and readily form salts with metals. 15. The are metals that are more reactive than the transition elements but less reactive than the alkali metals.
2 3 Li Lithium Na Sodium Be Beryllium Mg Magnesium Which element will react more readily with chlorine: sodium or magnesium? Why? 17. Which element is more like lithium in terms of properties: sodium or beryllium? Why? 18. Which element has more electrons in its highest occupied energy level: sodium or magnesium? 19. Which element has a lower melting point: lithium or beryllium? 20. Which element is closer to achieving noble gas configuration: magnesium or lithium? 21. Which element reacts more readily with fluorine: lithium or beryllium? Why?
3 For each choice of words, circle the one that best completes the sentence. 1. The shielding effect increases with increasing atomic number within a (period, group). 2. In any (period, group), the number of electrons between the nucleus and the outer energy level is the same. 3. Within a group, the nucleus has a stronger ability to pull on the outermost electrons in elements of (high, low) atomic number. 4. The more (positive, negative) the value of electron affinity is, the more easily the atom can take on an extra electron. 5. From left to right across a period, electron affinity values become more (positive, negative). 6. The halogens have the (most, least) negative electron affinity values. 7. The (electronegativity, electron affinity) of an atom is the tendency of an atom to attract electrons to itself when it is chemically combined with another element. 8. The (noble gases, halogens) are the most electronegative group. Use the following choices: a. increases b. decreases c. remains constant d. there is no pattern 9. Moving from top to bottom in a group, atomic radius tends to. 10. Moving from top to bottom in a group, shielding effect tends to. 11. Moving from top to bottom in a group, electronegativity tends to. 12. Moving from top to bottom in a group, electron affinity tends to. 13. Moving from top to bottom in a group, ionization energy tends to. 14. Moving from left to right across a period, atomic radius tends to. 15. Moving from left to right across a period, shielding effect tends to. 16. Moving from left to right across a period, electronegativity tends to. 17. Moving from left to right across a period, electron affinity tends to. 18. Moving from left to right across a period, ionization energy tends to. 19. Which atom has the more negative value for electron affinity, sodium or chlorine? 20. Which atom is more electronegative, fluorine or lithium? 21. Which atom has a greater ionization energy, nitrogen or bismuth? 22. Which atom exerts a stronger pull on its outermost electrons: calcium or arsenic? 23. Which atom has a larger atomic radius, fluorine or barium? 24. Which atom has a greater nuclear charge, boron or selenium?
