That is not true. Every element takes the form of a gas if it is sufficiently heated. In other words, all elements have some boiling point. For some elements the boiling point is very high, but it does exist.
Any metal can be in a gas form once a boiling point it will evaporate and become a gas
No, neon exists as a monatomic gas at standard temperature and pressure. It does not readily form diatomic molecules or other larger clusters like some other elements.
Water. Water(liquid), ice(solid), and water vapor(gas)
For most elements, a complete outer shell, like that of a noble gas, has eight electrons. There are exceptions. Helium, which is the most noble of the noble gases, has only two electrons in its outer shell. A few other light elements only need two (and hydrogen can also exist with no electrons at all, in the form of a naked proton, which is also a form of completion for the outer shell).

11 elements exist as gas in ordinary conditions
All group 18 elements (the noble gases) exist as monatormic gases at room temperature and standard pressure. All other elements form diatomic gases, if they exist as gas under the specified conditions. Among the listed elements there is only one noble gas: Argon
Group 0 Elements ( Helium, Neon, Argon...) do not form compounds because they have a complete Octet and are thus unreactive and exist as mono atomic elements
Any metal can be in a gas form once a boiling point it will evaporate and become a gas
All elements and compounds can exist as a gas if heated sufficiently.
liquid, gas, solid
Fluorine gas is one of the most reactive elements that exist and it will react with most metals.
Yes, like all elements boron can exist as a solid, liquid, or gas.
Hydrogen, nitrogen, oxygen, fluorine, chlorine, and all the noble gases exist as a gas at standard temperature and pressure.
No, neon exists as a monatomic gas at standard temperature and pressure. It does not readily form diatomic molecules or other larger clusters like some other elements.
Matter can exist in four forms: plasma, gas, liquid, solid.
