isra is analyzing the properties of several samples of elements to find out which sample is a metalloid. which set of properties most likely belongs only to a metalloid? forms basic compounds and is a solid has a high luster and is very brittle is a gas and has low electrical conductivity is brittle and forms acidic compounds
Answer
Answer:
D. is brittle and forms acidic compounds
Explanation:
Step1: Recall metalloid properties
Metalloids have properties intermediate between metals and non - metals.
Step2: Analyze option A
Many metals form basic compounds and are solids, not unique to metalloids.
Step3: Analyze option B
Some metals have high luster, so this is not exclusive to metalloids.
Step4: Analyze option C
Most metalloids are solids, not gases, and this property doesn't match.
Step5: Analyze option D
Metalloids are often brittle and can form acidic compounds, which is a characteristic set of properties for them.
