Which materials are typically used as thermal insulators

These are :

1.Fiber glass. It is made up of finely woven silicon and glass powder and is able to minimize heat transfer.

2. Mineral wool. This may refer to glass wool which is really fiberglass manufactured from recycled glass, or rock wool which is made from basalt,

3.Cellulose. This is made from recycled cardboard and is one of the most eco-friendly forms of insulation.

4. Polyurethane foam: While not the most abundant of insulation, polyurethane foams are an excellent form of insulation. 

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

um i think it might be a car?
