4:39 AD く < Science-9_Q2_Mod... till 99% Q Lesson 1 IONS: How Are They Formed? In the previous module, you have learned the different types of compounds based on their properties such as melting point, hardness, polarity and electrical and thermal conductivity. In this module, you will learn about ions and how they are formed. You are going to figure out what types of ions are formed when atom lose and gain electrons during chemical bonding. Here are some key questions for you to ponder after finishing this module: 1. What are ions and how are they formed? 2. What is the difference between cations and anions? 3. How is the formation of ions using Lewis Electron Dot Symbols (LEDS) shown? 4. How is the chemical formula based on the charges of ions written? What's In Let's recall your understanding of the different types of compounds based on their property. Write I if the statement describes an ionic compound, C if the statement describes a covalent compound. 1. It conducts electricity when dissolved in water. 2. It has a high melting point. 3. Does not conduct electricity. 4. Insoluble in water. 5. It has a low boiling point 6. It is formed through losing and gaining electrons. 7. Consist of positive and negative charged particles. 8. Bond between two nonmetals. 9. Bond between a metal and a nonmetal. 10. Formed through sharing of electrons. 3 CO_Q2_Science 9 Module 3 7/19 What's New Read the comic strip below.
