Compare the chemical properties of metals and non-metals .
Answers
Explanation:
1)metals reacts with acid to form salt and evolve hydrogen gas
non metal does not react with acid
2) metal are those which can easily lose its electron , therefore they are electropostive,
non metal are those which can easily gain electron , therefore they are electronegative
3) metals reacts with oxygen to form amphoteric oxide or basic oxide
non metal reacts with oxygen to form acidic oxide
4) metals are cation
non metals are anion
5) metal carbonate reacts with acid to form salt, co2 and water
nonmetal carbonate does not react with acid
6)
Answer:
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.
