Answer
Metals
$\Longrightarrow$ lustrous (shiny)
$\Longrightarrow$ Sonorous ( Make noise when striked)
$\Longrightarrow$ Good conductors of electricity
$\Longrightarrow$ Malleable and ductile
$\Longrightarrow$ Usually solid at room temperature ( Exception - Mercury)
Non Metals:
$\Longrightarrow$ Not lustrous (Have a dull appearance)
$\Longrightarrow$ Non sonorous
$\Longrightarrow$ Poor Conductors of electricity (Exception - graphite)
$\Longrightarrow$ Brittle
$\Longrightarrow$ Maybe solids, liquids or gases at room tempertaure
Work Step by Step
