Which properties are characteristics of metalloids?
a high electrical conductivity and a high melting point
b low electrical conductivity and a low melting point
c intermediate conductivity and a high melting point
d intermediate conductivity and a low melting point

Intermediate conductivity and a high melting point.

Option: C

Metalloids being the smallest class of elements, it usually comes between metals and non-metals i.e., the other two classes of elements. It means that metalloids possess properties of both metal and non-metals or mixture of properties of both the classes. Some properties of metalloids processes from either metals or metalloids. Like metals conduct electricity and heat but non-metals do not, but some metalloids can usually at higher temperatures, then the metalloids are known as semiconductors. So we can conclude that metalloids tend an instant conductivity and a high melting point.

i just took the quiz

no statements but ok.

the statement that best describes the idea of manifest destiny that was used in the 19th century would be that "it was fate that the united states would continue to  expand westward," since people thought the us was "destined" to do so. 

yup! you are correct it is b.
