Ductility, in the case of gases, makes no sense.
A gas does not have any ductility.
Xenon is a gas and the concept of ductility makes no sense for a gas.
No, xenon is a noble gas and is typically not considered ductile. Ductility refers to a material's ability to deform under stress without breaking, and because xenon is a gas at room temperature, it does not possess the physical properties associated with ductility.
Hardness is the opposite of ductility.
Ductility is a physical property.
Xenon is a gas at any reasonable temperature (a melting point of around 161K) and is only solid in a range of 4 degrees on the Celsius and Kelvin scales. It does not become metallic until well over 150 GPa of pressure. At this point, it may well be malleable, but for all intents and purposes it is not.
when ductility increase hardness decrease
No. Ductility is a property whereas salts are a kind of chemical!
When you mix fluorine with xenon, the fluorine can react with xenon to form xenon fluorides, such as xenon tetrafluoride (XeF4) or xenon hexafluoride (XeF6). These xenon fluorides are generally unstable and highly reactive compounds.
No, iodine is a brittle solid at room temperature and does not exhibit ductility.
It is impossible to test the ductility of francium; but probable Fr is not ductile.
Xenon is a noble gas. I would think any compounds would be hard to make with using Xenon.
