Helium, Neon, and Argon are the most non-reactive elements known. Though it is possible to make them react with other elements, it is extremely difficult and can only be achieved under precise laboratory conditions.
The Noble gasses.
yes
It can react with Hydrogen, Litium and some unknown elements.
All of them tend not to react with each other until you get lower down the group
It won't react with any of the other elements.
Group-18 elements least react with other elements. They are inert in nature. They are called noble gases.Elements in group 18 are less likely to react with any other elements. This group is made out of the noble gases. Its members are He, Ne, Ar, Kr, Xe and Rn.
They don't react with any other elements.
Inert (or noble) gasses, such as helium, argon, neon, etc.
No. Kryptonite is a nobel gas, and doesn't react with any other elements.
Yes, nitrogen can react with other elements and compounds to form various nitrogen-containing compounds, such as ammonia, nitric acid, and nitrogen oxides.
Most elements will react with at least one other substance. Certain groups of elements have certain substances that they react or don't react with. For Example, Group 1 - Alkali Metals all react vigourously with water. The Inert Gases (exc. Radon) are all highly unreactive and react with a very small amount of substances, if any.
No. Kryptonite is a nobel gas, and doesn't react with any other elements.
