![]() ![]() Which particle has the larger radius in each atom/ion pair? Circle your answer. Rank the following elements by increasing electronegativity: sulfur, oxygen, neon, aluminum. Rank the following elements by increasing atomic radius: carbon, aluminum, oxygen, potassium. Explain the relationship between the relative size of an ion to its neutral atom and the charge on the ions. Directions: Use your notes to answer the following questions. S is above Te on the periodic table Te is larger because as you go down the column, the atoms get larger. What is the difference between a cation and an anion? 8. Solution Si is to the left of S on the periodic table it is larger because as you go across the row, the atoms get smaller. What is the periodic trend for atomic size from top to bottom in a group. Which atom in each pair has the larger atomic radius a) Li or K b) Ca or Ni c) Ga or B d) O or C e) Cl or Br f) Be or Ba g) Si or S h) Fe or Au. Li: 1s22s1 K: 1s22s22p63s23p64s1 O: 1s22s22p4 S: 1s22s22p63s23p4 K has a greater number of energy levels than Li, which explains the difference in size between the 2 atoms. ![]() The size of atoms increases down a group in the periodic table. Arrange the following in order of increasing atomic radius atomic radius. Use the periodic table and your knowledge of periodic trends to answer the following questions. Answers to Worksheet on Ionic and Atomic Size Trends 1. Why do atoms get larger as you move down a group? 5. Why do atoms get smaller as you move left to right in a period? 4. Students should draw a picture of a circle, indicating the. Draw a picture to support a written definition of the word radius. You will be asked to interact with select atoms as you investigate these concepts. What is the periodic trend for atomic size from top to bottom in a group? From left to right in a period? 3. In this investigation you will examine several periodic trends, including atomic radius, ionization energy and ionic radius. a) Li or K b) Ca or Ni c) Ga or B d) O or C e) Cl or Br f) Be or Ba g) Si or S h) Fe or Au 2. Which atom in each pair has the larger atomic radius? Circle your answer.
