Answer 2

${\tt{\small{\purple{\boxed{\blue{\red{\pink{\boxed {\underline{\bf{\red{\bigstar}{Metal}}}}}}}}}}}}$

${\pink{\implies}}$Metals are the natural elements which are solid, lustrous, opaque and with high density.

${\pink{\implies}}$They are lustrous (shiny surface).

${\pink{\implies}}$They generally have 1 to 3 valence electrons in the outermost shell of their atoms.

${\tt{\small{\purple{\boxed{\blue{\red{\pink{\boxed {\underline{\bf{\red{\bigstar}{Non \: Metal}}}}}}}}}}}}$

${\pink{\implies}}$Non-metals are the natural elements that lack metallic properties.

${\pink{\implies}}$They are not lustrous.

${\pink{\implies}}$They generally have 4 to 8 valence electrons in the outermost shell of their atoms.
