Answer 1

metals are generally hard whereas non metals can soft
metals have shiny lustre and non metals have dull lustre

Answer 2

Answer:

Answer:

Metals

In the periodic table, you can see a stair-stepped line starting at Boron (B), atomic number 5, and going all the way down to Polonium (Po), atomic number 84. Except for Germanium (Ge) and Antimony (Sb), all the elements to the left of that line can be classified as metals.

These metals have properties that you normally associate with the metals you encounter in everyday life:

They are solid (with the exception of mercury, Hg, a liquid).

They are shiny, good conductors of electricity and heat.

They are ductile (they can be drawn into thin wires).

They are malleable (they can be easily hammered into very thin sheets).

All these metals tend to lose electrons easily. The following figure shows the metals.

Nonmetals

Except for the elements that border the stair-stepped line, the elements to the right of the line are classified as nonmetals (along with hydrogen). Nonmetals have properties opposite those of the metals.

The nonmetals are brittle, not malleable or ductile, poor conductors of both heat and electricity.
