Which of the following is a property commonly associated with metalloids?
A
They are excellent conductors of heat and electricity.
B
They are typically found as gases at room temperature.
C
They have intermediate electrical conductivity between metals and nonmetals.
D
They are generally malleable and ductile.
Verified step by step guidance1
Understand that metalloids are elements with properties intermediate between metals and nonmetals.
Recall that metals are typically good conductors of heat and electricity, malleable, and ductile, while nonmetals are poor conductors and often found in gaseous states at room temperature.
Recognize that metalloids do not fit perfectly into either category but instead have electrical conductivity that is between that of metals and nonmetals.
Identify that the property 'They have intermediate electrical conductivity between metals and nonmetals' correctly describes metalloids.
Note that the other options describe characteristics typical of metals or nonmetals, not metalloids.
