A: Is non-malleable, non-ductile and a poor conductor of electricity Non-metallic element.
- The non-metals are elements on the right of the periodic table.
B: Has lustre, is malleable and ductile and a good conductor of heat Metallic element.
- Any of several chemical elements that are usually shiny solids that conduct heat or electricity and can be formed into sheets etc are called metals.
C: Is unreactive and inert and present in traces in air Noble gas.
- Noble gases generally do not react.
D: Shows properties of both metals and non-metals Metalloid.
- An element (e.g. arsenic, antimony, or tin) whose properties are intermediate between those of metals and solid non-metals or semiconductors.
