It depends on which non metals you mean. The ability to scratch a material depends on its hardness relative to the material you use to scratch it with. With your nails you can scratch materials softer than your nails, like some plastics and minerals. But nothing can scratch in diamond because it's the hardest material there is, but in turn diamond can scratch all other materials, since they're softer that diamond including all metals and non metals.
So although most metals are relatively soft, there are many non metals that are softer that some metals.
Trivia:
the softest metal is Mercury with a hardness of 0 (it's liquid at room temperature)
The hardest metal is carbon steel with a hardness of around 8 to 9
The softest mineral is talc with a hardness of 1
The hardest mineral is diamond with a hardness of 10 (a form of pure carbon)
Non metals cannot emit a colored light.
all are non metals
metals on left, non-metals on right, some others in middle.
Atoms of non-metals usually gain or share electrons when they react with other atoms.
Non-metals, metals and semiconductors. Metals are on the left, non-metals on the right, and semiconductors sitting near the staircase line that divides the metals and non-metals.
Non metals cannot emit a colored light.
no you cant because they dont have the ability to do that.

quickly oxidation
My opinion would be metal. Since non metals are brittle and dull, I disagree with the non-metals.
the physical characteristics of a non metal are not ductile meaning it cant be drawn into wires non mallable meaning it cant be rolled into thin sheets also its poor in luster meaning its not shinny also nonmetals are brittle
They are in between the metals and non metals
No beace it cant be scratched and if cant be scratch than how is it going to break
The most reactive non metals are Halogens which may combine most of the metals as well as non metals.
