Correct
Neon is a noble gas, which signifies that it has eight valence electrons (a filled valence shell).
Part C
Identify which electrons from the electron configuration are included in the Lewis symbol.
ANSWER:
Correct
The valence electrons of Lewis symbols usually correspond to the highest quantum number. The highest quantum level of neon is .
In comparison, the Lewis symbol of the sulfide ion, , would show the 8 valence electrons corresponding to . However, sulfur is also capable of
having an expanded octet because it can use the orbitals, so the Lewis symbol of the sulfate ion, , has 12 valence electrons in the bonds around
sulfur.
