Why doesn't potassium bond with neon to form a compound?

Answer 1

Helium is considered a stable element (you can tell because it is a Nobel gas, in group VIII of the Periodic Table), as it has a full compliment of electrons in its energy level. Ionic bonds will only be formed when a metal and a non-metal lose/gain electrons and become stable as a compound. There is no point in helium losing or gaining electrons with other elements because it's already stable.

Answer 2

Potassium is an alkali metal, and neon is an inert or noble gas. The inert gases have full valence shells, and this will cause them to, in general, avoid chemically reacting or bonding with any other elements. Potassium (K) is quite reactive, but neon isn't. Expose metallic potassium to air and it will react with the water in air. Put that potassium in a neon (Ne) atmosphere and nothing happens.

Answer 3

Neon is a Noble Gas, and they seem to be the odd elements out. They are almost completely non-reactive in any way, and commonly exist single atoms floating around in the air, unlike oxygen or nitrogen which almost never exist as single atoms but are commonly diatomic. Neon will not react with potassium because it is completely non-reactive.

Answer 4

Although potassium is a very heavily reactive alkali metal (making water explosively 'burn') the other contrarily component is very, very NONreactive compound: it is called one of the 'noble' monoatomic gases.

Answer 5

Neon is a non-reactive gas. There are only a few covalently bonded neon compounds known and none of those contain potassium.
