The Octet Rule Flashcards
1
Q
Define the octet rule.
A
When bonding occurs, atoms tend to reach an electron arrangement with eight electrons in the outermost energy level
2
Q
Why do the noble gases not react?
A
Because they have stable electron configurations
3
Q
Noble gases don’t react, what are they often called because of this?
A
Inert gases
4
Q
What is the aim when elements react together to form compounds?
A
Their atoms change their electrons to try to end up with eight electrons in their outermost energy level
5
Q
Give the two exceptions to the Octet Rule.
2
A
Transition metals do not usually obey the octet rule
Elements near helium tend to achieve the electron arrangement of helium with two electrons in the outer energy level rather than the eight electrons of the other noble gases
