What is the octet rule in chemistry?
What is the octet rule in chemistry?
- It states that the valence shell of noble gases contains eight electrons.
- It states that atoms lose, gain, or share electrons to attain the electronic configuration ns2np6 of the nearest noble gas. (correct)
- It states that all atoms have eight valence electrons.
- It states that atoms bond to attain the ns2np6 electron configuration of the nearest noble gas.
Why are noble gases generally unreactive?
Why are noble gases generally unreactive?
- Due to their high ionization energies and low electron affinity. (correct)
- Because they have empty valence shells.
- Due to their strong attraction to other atoms.
- Because they tend to lose electrons in reactions.
