METAL
a solid material which is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity (e.g. iron, gold, silver, and aluminium, and alloys such as steel).
NON METAL
Seventeen elements are generally classified as nonmetals: most are gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon); one is a liquid (bromine); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine).

HEY BUDDY...
GOOD MORNING...♥
METALS :-
•ALL THOSE ELEMENTS WHICH FORM POSITIVE IONS BY LOSING ELECTRONS ARE CALLED METALS...THEY HAVE 1 TO 3 ELECTRONS IN THEIR VALENCE SHELL...
•EXAMPLE-ZINC,ALUMINIUM,MAGNESIUM AND SODIUM....
NON-METALS :-
•ALL THOSE ELEMENTS WHICH FORM NEGATIVE IONS BY GAINING ELECTRONS ARE CALLED NON-METALS...THEY HAVE 4 TO 8 ELECTRONS IN THEIR VALENCE SHELL....
•EXAMPLE-CARBON,SULPHUR,HYDROGEN AND OXYGEN...
HOPE IT HELPS...!!!
HAVE A GRT DAY AHEAD...^_^
