Answer:
Basis for Comparison Metals Non-Metals
Number of electrons Contains 1,2 or 3 electrons in valence shell (except hydrogen) Contains 4, 5, 6 or 7 electrons in valence shell.
Conducting property Good conductors Bad conductors
Tensile strength High Low
Melting and Boiling point High Comparitively very low
Existence in periodic table Left side Right side
Nature Electropositive Electronegative
Bond Metallic bond Covalent bond
State Generally solid (exception mercury and gallium) Solid, liquid and gas
Density High Low
Forms Cation Anion
Malleability and Ductility These are malleable and ductile These are non-malleable and non-ductile in nature.
Structure Hard Soft
