1. Love Story of: Sodium Princess & Chlorine Prince

2. Once upon a time, there was a very memorable love story between the beautiful Sodium princess and the talented Chlorine prince. Sodium is the princess of the country named Solid, which is far away from the country Gas of Chlorine prince. However, they were attracted to each other because of the number of electrons they have i n their outermost shells. Solid is a very poor country in the Alkali Earth Metal planet. Therefore, the princess just have only one electron in her valence but the prince of the rich Gas country has 7 electrons. However because of the opposite attraction, their love became stronger every day.

3. Day by day, because of her deep love toward the prince, the princess tried her best to enrich herself to become a Gas citizen like the prince. She converted herself to become Gas citizen by using equation: After successfully became a Gas citizen, she tried to find her lover, the Chlorine prince to marry him. Unfortunately, they have to face with one more problem. The prince has to take care of his twin brother who is Chlorine too and these two Chlorine Cl 2 can’t live without each other. So, the prince had to add more energy to get apart from his brother and become an independent Chlorine prince.

4. Difficulties didn’t stop. The prince had also to gain more energy to become ion like the princess so they can get married. After all, the Sodium princess and the Chlorine prince could get marry happily and born their famous child named Sodium Chloride who has a nickname NaCl . The End .

5. QUESTIONS 1. Who are the characters in the story? 2. Why they’re both attracted to each other? 3. How NaCl is being formed? 4. What Science concept is the story about?

6. C OVALENT & IONIC BONDING

7. COVALENT BOND share electrons equally between atoms occur between two non-metals made of molecules ( solid, liquid or gas) does not conduct electricity have low boiling and melting points 100% covalent molecules can be dissolved in oil, but not in water involves organic molecules

8. COVALENT BOND A compound composed of molecules is called molecular compounds . Water and carbon monoxide are molecular compounds. C O

9. COVALENT BOND EXAMPLE O 2 oxygen

10. COVALENT BOND EXAMPLE CH 3 CH 2 OH ethanol

11. COVALENT BOND EXAMPLE H 2 O water

12. COVALENT BOND

13. COVALENT BOND EXAMPLE O 3 ozone

14. IONIC BOND transfer electrons occur between metal and non-metals it made of ions ( crystal solid) conducts electricity when melted or dissolved have high boiling and melting points many dissolve in water not in oil involves inorganic molecules

15. IONIC BOND

16. IONIC BOND EXAMPLE LiF lithium flouride

17. IONIC BOND EXAMPLE NaF sodium fluoride

18. IONIC BOND EXAMPLE CaO calcium oxide
