which propertys do maloids share with nonmetals
A. both are brittel
B. both are shiny
C. both have low melting points *****
D. both are very conductive
which lists only metalloids
A. (As) (S) (Po)
B. (Sb) (Te) (Ga)*****
C. ( B) (Ge) (Te)
D. (Po) (Al) (Si)
someone please help meh i'm begging you if i don't do good on this test i'll get in trouble
To determine which properties metalloids share with nonmetals and to identify a list of metalloids, we can refer to the periodic table and the characteristics of these elements.
Metalloids are elements that have properties of both metals and nonmetals. They typically exhibit characteristics of both and can behave as either a metal or a nonmetal depending on the conditions.
To find the properties shared between metalloids and nonmetals:
A. Both being brittle is not a property shared between metalloids and nonmetals. Nonmetals can indeed be brittle, but metalloids can also have varying degrees of brittleness or flexibility.
B. Shiny or lustrous appearance is a property commonly associated with metals, so it is not shared by metalloids.
C. Low melting points - This is a property shared by metalloids and nonmetals. Typically, both metalloids and nonmetals have lower melting points compared to metals, making this the correct answer.
D. Very conductive - This property is not shared by metalloids and nonmetals. Nonmetals are generally poor conductors of electric current, while metalloids can have varying degrees of conductivity.
The correct answer is C - both metalloids and nonmetals share the property of low melting points.
Now let's identify the list that consists only of metalloids:
A. (As) (S) (Po) - Arsenic (As) is a metalloid, but both sulfur (S) and polonium (Po) are nonmetals.
B. (Sb) (Te) (Ga) - Antimony (Sb) and tellurium (Te) are both metalloids, while gallium (Ga) is a metal.
C. (B) (Ge) (Te) - Boron (B) is a metalloid, while germanium (Ge) is also a metalloid. However, tellurium (Te) is a nonmetal.
D. (Po) (Al) (Si) - Polonium (Po) is a metalloid, aluminum (Al) is a metal, and silicon (Si) is a metalloid.
The correct answer is B - the list (Sb) (Te) (Ga) consists only of metalloids.
