Potassium = Great conductor of heat and electricity

Neon = Non reactive

Boron = has properties of both metals and non metals

Barium = Malleable and highly reactive

Explanation:

Potassium = Great conductor of heat and electricity

Potassium is soft metal and has low melting point. It is white silvery luster with great heat conducting properties.

Neon = Non reactive

Neon is present in group eighteen. It is noble gas. Its outer electronic shell is completely filled that's why it is non reactive.

Boron = has properties of both metals and non metals

Boron is metalloid and behave like both metals and non metals.

Barium = Malleable and highly reactive

Barium is belong to group 2A. It is alkaline earth metal. It is highly reactive towards other elements such as oxygen, fluorine, chlorine , etc.
