Essential Questions - 21st Century Skills and Readiness Competencies (District):
1a. How can various substances be classified as ionic or covalent compounds?
1b. What will happen when an element gains, loses, or shares valence electrons to
achieve noble gas configuration?
2a. What are the different types of bonds and what role do electrons play in forming
them?
2b. What types of elements form ionic covalent bonds and how do the electrons
behave?
3. Where can you find ionic and covalent bonding, for example, in your house?
4. What kind of information is needed to identify chemical bonding in an
unknown substance?
5. How do observations of physical and chemical properties help you to predict their
bonding classification?
Evidence Outcomes (District):
