Which of the following is a property of metals that is due to the delocalized electrons
a. transparency
b. dull appearance
c. brittle
d. good conductor

Good conductor

Explanation:

Metals form metallic bonds. They are also sometimes called 'a sea of electrons'. Basically, metal cations are surrounded by a sea of closely packed valence electrons. This close packing lets the particles of a metal interact much more efficiently and transfer heat or electric current efficiently. The valence electrons and metals ions are also moving to some extent, so besides being packed efficiently, they can also interact and collide to transfer electricity and heat.

This makes metals good heat and electric conductors.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
