1 Chapter 6.1 Assessment Chapter 6 Page 164 Questions 1-8

2 Question 1: When is an atom least likely to react?

3 Question 1: Answer When is an atom least likely to react? When the highest energy level of an atom is filled with electrons

4 Question 2: Describe one way an element can achieve a stable electron configuration?

5 Question 2: Answer Describe one way an element can achieve a stable electron configuration? Through the transfer of electrons between the atoms

6 Question 3: What characteristic of ionic bonds can be used to explain the properties of ionic compounds ?

7 Question 3: Answer What characteristic of ionic bonds can be used to explain the properties of ionic compounds ? The strong attraction among ions within a crystal lattice

8 Question 4: Use Ionization energy to explain why metals lose electrons more easily than non- metals ?

9 Question 4: Answer Use Ionization energy to explain why metals lose electrons more easily than non- metals ? Metals have a lower ionization energies than non-metals. The Lower the ionization energy, the easier it is to remove an electron from an atom.

10 Question 5: Why is a rock salt crystal likely to shatter when struck ?

11 Question 5: Answer Why is a rock salt crystal likely to shatter when struck ? When ions with the same charge are pushed close together, they repel one another

12 Question 6: What will the ratio of ions be in any compound formed from a group 1A metal and a group 7A non-metal ?

13 Question 6: Answer. What will the ratio of ions be in any compound formed from a group 1A metal and a group 7A non-metal ? The ratio will be one to one because a group 1A metal loses one electron to achieve a stable electron configuration.

14 Question 7: Why do ionic compounds include at least one metal?

15 Question 7: Answer Why do ionic compounds include at least one metal? One element in an ionic compound must form cations, but non-metals tend to form anions.

16 Question 8: Based on their chemical formulas which of these compounds is not likely to be an ionic compound : KBr, SO2, or FeCl3 ? Explain your answer.

17 Question 8: Answer SO2 because sulfur and oxygen are both non-metals and unlikely to form cations
