Which best explains why metal cooking utensils often have plastic coating on the handles

Metal solids contain a positively-charged cation surrounded by a "sea" of delocalised, negatively-charged electrons.

The electrons are able to move freely, and hence transfer kinetic energy throughout the implement at a much quicker rate than non-metals.

Plastic is made of non-metals (Mostly carbon and hydrogen) and therefore is a poor thermal conductor.

Therefore, by coating the metal utensil in plastic, the rate of heat energy transfer to the person in contact's hand is decreased.

All the elements are arranged by melting points on the periodic table. in row they go from metals to gasses. in the row from sodium to argon, sodium is more reactive than the one on its right, magnesium.
