What it is
Metals are shiny, bendable conductors of heat and electricity; non-metals are dull, brittle insulators.
Answer
Metals are generally lustrous (shiny), malleable and ductile, good conductors of heat and electricity, and sonorous. Non-metals are usually dull, brittle (break easily) and poor conductors of heat and electricity. For example, iron is a shiny conductor while sulphur is a dull, brittle insulator.
- •Metals: lustrous, malleable, ductile, good conductors, sonorous
- •Non-metals: dull, brittle, poor conductors
- •Example: iron (metal) vs sulphur (non-metal)
Why learn this
It's why wires are made of copper (a metal) and a matchstick tip uses sulphur (a non-metal).
