Non metals aren't ductile because non metals lack all properties of metals and metals are ductile. In other words, non-metals are non-malleable and non-ductile. Non-Ductile: Non metals are non-ductile because they cannot be melted and drawn into thin wires.

They are brittle in nature. Ductile Metals + properties give you a broad overview of these metals from multiple angels. There are materials that are elastic like rubber and there are polymers that are plastic but ductility means the ability to be drawn into wire - iron, steel, copper, gold, silver, platinum etc. Metals are ductile; which means they can be stretched out into wire, and non-metals are nonductile. The most ductile metal is platinum and the most malleable metal is gold. are ductile metals. Non-metals usually have 4, 5, 6 or 7 electrons in their outermost shell. Metals differ from nonmetals merely in that they have a positive oxidation number.

Non-metals are the elements which form negative ions by accepting or gaining electrons. [7] [8] When highly stretched, such metals distort via formation, reorientation and migration of dislocations and crystal twins without noticeable hardening. The chart below displays a comparison of the physical and chemical properties of the metals and nonmetals. For example: Sulphur and phosphorous. Supplementary facts like side effects & benefits of these metals, their abundance in earth's crust, their presence in the human body, etc. Brittle solids—not malleable or ductile; Little or no metallic luster; Gain electrons easily; Dull, not metallic-shiny, although they may be colorful; Lower melting points and boiling point than the metals ; Comparing the Metals and Nonmetals. These non-metals are in the form of powder and cannot be beaten. Moreover, enthusiasts are also catered with the detailed breakdown of the atomic, optical and chemical behaviour of the metals. metals in most of the ... (C, black P, S and Se) are brittle solids at room temperature (although each of these also have malleable, pliable or ductile allotropes). Non-metals usually have 4, 5, 6 or 7 electrons in their outermost shell. Where stress is applied on non-metals, they shatter into pieces.
