Question

sample color state of matter at room temp texture conducts electricity
sample #1 shiny, yellow solid malleable yes
sample #2 dull, brown solid brittle no
sample #3 dull, green solid malleable no
sample #4 brittle, white solid brittle no
your science teacher is cleaning out the storage room and finds unlabeled samples of elements. based on the properties listed in the table, which samples would you classify as metals?
sample #1
sample #2
sample #3
sample #4

Explanation:

Step1: Recall Metal Properties

Metals are typically shiny (luster), solid at room temp (except Hg), malleable/ductile, and conduct electricity.

Step2: Analyze Each Sample

• Sample #1: Shiny, solid, malleable, conducts (yes) → matches metal properties.
• Sample #2: Dull, solid, brittle, no conductivity → non - metal.
• Sample #3: Dull, solid, brittle, no conductivity → non - metal.
• Sample #4: Dull, solid, brittle, no conductivity → non - metal.

Answer:

Sample #1
