What is the difference between metal and non metal in their chemical properties |
| Answer» \xa0\t Metals Non-metals\xa0Metals are\xa0electro-positive.Non-metals are electronegative.Metals reacts with oxygen to form basic oxides. 4Na+O2\u200b→2Na2\u200bONon-metals react with oxygen to form neutral or acidic oxide. C+O2\u200b→CO2\u200bMetal 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+2H2\u200bO→2NaOH+H2\u200bNon-metals do not react with water.Metals react with dilute acids to form salt and\xa0H2\u200b.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\u200b+e−→Cl−\xa0\t\xa0 | |
