ANSWER...
METALLIC CHARACTER REFERS TO THE ELEMENT WITH VALENCE ELECTRONS 1,2,3. HAVING HIGH MELTING AND BOILING POINT AND LIBERATES HYDROGEN WITH ACIDS AND LOSES ELECTRONS TO BE STABLE LIKE NEAREST NOBLE GAS
DURING A GROUP AS WE MOVE DOWNWARDS THE MENTALLIC CHARACTER INCREASES.
BECAUSE...
ELECTRONI AFFINITY DECREASES.
IONISATION POTENTIAL DECREASES .
ELECTRON NEGATIVITY DECREASES.
SO TENDENCY TO LOSE ELECTRON RATHER THAN GAINING INCREAES..
