Question

Answer the following questions about elements and their properties based on their position on the periodic table. 1. For main group elements (A), the number of valence electrons is indicated by which number on the periodic table? 2. How many valence electrons does a neutral atom of sulfur contain? 3. Which main group has 2 valence electrons? 4. As you down a group (column), what happens to the size of the atoms? 5. Which atom would have greater atomic radius, Ge or Se? 6. Which atom would have greater electronegativity, F or Br? 7. List the following atoms in order of increasing ionization energy (Ar, Al, P). 8. Which atom would have greater metallic character, Sr or I? 9. List the following atoms in order of increasing electron affinity (O, Po, Ne) 10. Which atom would have greater atomic radius, Ga or Sn?
