One of my questions asks me to find the volume of neon gas. I thought neon didn't attach with other atoms because it had a full valence shell, how would it form into a gas? What would the formula be? N2, N3 ?

Neon IS a gas and it doesn't form compounds if that is what you mean by attaching itself to other atoms. There must be more to the question than simply what volume. Are there several volumes? change of temperature? change of pressure? Post the entire question and we can help you through it.

I think I understand it now. They also said at STP. I didn't notice that at first. Thanks :)

Neon gas does not form molecules like nitrogen gas (N2) or nitrogen triatomic (N3). Neon is an example of a noble gas, which means it exists as individual atoms rather than bonding with other atoms to form molecules.

Neon gas is composed of individual neon atoms, and its formula is simply Ne. This means that each unit of neon gas consists of a single atom of neon.

Now, regarding the volume of neon gas, we can use the ideal gas law to calculate it. The ideal gas law is expressed as:

PV = nRT

Where:
P = pressure of the gas
V = volume of the gas
n = number of moles of gas
R = ideal gas constant
T = temperature of the gas

If you are given the pressure, temperature, and number of moles of neon gas, you can solve for the volume V by rearranging the equation:

V = (nRT) / P

Remember to make sure that the units for pressure, volume, temperature, and moles are consistent (e.g., P in atmospheres, V in liters, T in Kelvin, and n in moles) when performing the calculation.

It's important to note that the volume of neon gas will depend on the specific conditions (pressure and temperature) under which it exists.
