Barium - A) Great conductor of heat and electricity Potassium - B) Malleable and highly reactive Boron - C) Has properties of both metals and nonmetals Neon - D) Nonreactive gas Let's look at each element and it's place on the periodic chart to see what matches. Potassium - This is on the far left column for alkali metals. This means it's highly reactive and since it's a metal, it's both malleable and conductive. Looking at the available options, "B) Malleable and highly reactive" is the best choice. Barium - This element is in the second column from the left, so it's a fairly reactive metal, but not nearly as reactive as Potassium above. So "A) Great conductor of heat and electricity" is the best choice here, although I wouldn't call it "great". The resistivity of barium is about 20 times larger than copper. Boron - This element is about in the middle of the periodic chart, so it does have the properties of both metals and nonmetals. So "C) Has properties of both metals and nonmetals" is the best choice. Neon - This is in the far right column for noble gasses. Very non-reactive. So "D) Nonreactive gas" is the best choice.

Great conductor of heat and electricity: Barium

Malleable and highly reactive: Potassium

Has properties of both metals and nonmetals: Boron

Nonreactive gas: Neon

  • The group of elements that has the ability to conduct electricity and heat is Group I or II. Barium belongs to Group II and has been able to conduct electricity and heat.

  • The group I elements are malleable and highly reactive. Potassium belongs to group I metal and is highly malleable and reactive.

  • The noble gases have the properties of both metal and non-metal. The Boron has properties of both.

  • The noble gases are non-reactive gases. Thus neon has been the non-reactive gas.
