A student is trying to classify an unidentified, solid gray material as a metal or a nonmetal.
Which question will best help the student classify the material?
A) Is the material malleable or ductile?
B) Does the material feel hard to the touch?
C) Will the material float in water?
D) Does the material feel rough or smooth?

Option A

Is the material malleable or ductile will best help the student classify the material

Explanation:

Metals are elements enduring or owning the properties of existing polished, strong, fusible, flexible, ductile, etc. Malleability applies to the feature of metals by which they can be pounded into flat films. Ductility relates to the features of metals below which they can be rendered into fragile wires.

Non-metals occupy no malleability. They are non-ductile. So if the student distinguishes the statement to the subject "Element is malleable or ductile?" they can efficiently recognize whether the element is metal or nonmetal.
