distinguish between Metal and non metal based on the following properties reaction with dilute acid ,reaction with base , reaction with water
Answers
Explanation:
Metals Non-metals Metals are electro-positive .Non-metals are electronegative. Metals reacts with oxygen asic oxides.
4Na+O2→2Na2O
Non-metals react with oxygen to form neutral or acidic oxide.
C+O2→CO2
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+2H2O→2NaOH+H2
Non-metals do not react with water.Metals react with dilute acids to form salt and H2.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.
Cl2+e−→Cl−
