Lesson: Types of Chemical Bonding Chemistry • Second Year of Secondary School

Students will be able to

• describe the concept of valency and identify the valence electrons for an element,
• describe the different types of chemical bonding,
• explain the differences and similarities between the different types of chemical bonding,
• describe and explain the octet rule and its relation to both valency and chemical bonding,
• calculate the number of electrons in the outer shell a metal can lose to achieve a full outer shell,
• calculate the number of electrons in the outer shell a nonmetal can obtain to achieve a full outer shell,
• write the Lewis structure for an atom and an ion,
• use the Lewis structure of an atom or ion to describe and predict the type of chemical bonding that will occur,
• calculate the number of covalent bonds a nonmetal can form based on its group in the periodic table.
