Explanation:
Answer: d: They are poor conductors of heat and electricity
.
Explanation:
Although is common knowledge that metals are characterized by high electrical conductivity and heat conductivity, these properties can be justified by looking at the metallic bonding.
<u>In a metal, the bonding electrons are delocalized over the entire crystal</u>. In fact, metal atoms in a crystal can be imagined as an array of positive ions immersed in a sea of delocalized valence electrons.<u>The mobility of the delocalized electrons makes metals good conductors of heat and electricity.
</u>
