An element is stable when it has a full outershell.
Generally, most shells after the first can hold 8 electrons.
The first shell can only hold 2
So in order for neon to be stable it must have a full outer shell
The first shell can hold 2
Neon has 10 electrons
10-2=8
The second shell can hold 8
And neon has 8 electrons left
So it must have 8 valence electrons to be stable

Answer:
The molecules of solid CO2 are much closer together than the molecules of CO2 gas.
Answer:
Silver Nitrate is very soluble in water.
P1V1 = P2V2
P1 = 720 mmHg
V1 = 450. mL
P2 = 760 mmHg (this is the pressure at STP)
Use these to solve for V2:
(720)(450) = 760V2
V2 = 426 mL
