Question

1a. shane tested the properties of four samples and recorded data in the chart.
observation of unknown substances

unknown	1	2	3	4
appearance	shiny	black and gritty	blue	clear
observation	bends easily	snaps easily in small pieces	bends and snaps back to its original shape	shatters easily

Explanation:

Since the problem is not fully stated (e.g., what specific question is being asked about the chart, like identifying a metal, non - metal, or metalloid among the samples, or something else), we can't provide a complete solution. But if we assume a common question like "Which sample is most likely a metal?"

Step1: Recall metal properties

Metals are generally shiny, conduct electricity, and are malleable (bend easily without breaking) or ductile.

Step2: Analyze each sample

• Sample 1: Shiny (appearance of metal), conducts electricity (yes), bends easily (malleable behavior).
• Sample 2: Black and gritty, doesn't conduct electricity, snaps easily (brittle, non - metal like).
• Sample 3: Blue, doesn't conduct electricity, bends and snaps back (maybe a non - metal or a different material, not typical metal).
• Sample 4: Clear, shatters easily (brittle, non - metal like).

So Sample 1 has the most metal - like properties.

Answer:

Sample 1
