Answer:
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.
