Explain any chemical properties of metals and nonmetals with one activity (with diagram) |
|
Answer» Metals Non-metals Metals are electro-positive. Non-metals are electronegative.Metals reacts with oxygen to FORM basic oxides.4Na+O 2 →2Na 2 ONon-metals REACT with oxygen to form neutral or acidic oxide.C+O 2 →CO 2 Metal oxides and hydroxides bonds have ionic bonds. Non-metal oxides and hydroxides have covalent bonds.Metals react with water to form hydroxide and hydrogen.2Na+2H 2 O→2NaOH+H 2 Non-metals do not react with water.Metals react with dilute acids to form salt and H 2 . Non-metals do not react with dilute acid and they can not displace hydrogen.Metals react as REDUCING agent by DONATING electrons.Na→Na + +e − Non-metals are oxidizing agents that can GAIN the electrons.Cl 2 +e − →Cl − |
