Question 1.
What is the octet rule?
Show hintHide hint
Think about how atoms achieve stability.
Question 2.
Which atom only needs two electrons to be stable?
Show hintHide hint
Consider the smallest element.
3Question 3.
What does the octet rule state?
- Atoms must have a full outer shell of ten electrons.
- Atoms gain, lose, or share electrons to have eight electrons in their outer shell.
- Atoms are always stable regardless of the number of electrons.
Show hintHide hint
Focus on the number eight!
4Question 4.
True or False: Hydrogen follows the octet rule by seeking a full outer shell of eight electrons.
- True
- False
Show hintHide hint
Think about hydrogen's unique position on the periodic table.
Question 5.
Consider two different elements, Lithium (Li) and Fluorine (F). Describe how each would achieve a full outer shell through bonding and explain the type of bond formed.
Show hintHide hint
Think of their positions in the periodic table!
Question 6.
Draw the Lewis dot structures for carbon (C, with four valence electrons) and oxygen (O, with six valence electrons). Show how they can share electrons to fulfill the octet rule.
Show hintHide hint
Remember the shared pairs count for each atom's octet!
