Question 14
Differentiate between metal and non-metal on the basis of their chemical properties.
MetalNon−MetalMetals are electropositive,readily lose valence electronsNon−metals are electronegative,readily accept electronsOxides of metals are basic in natureOxides of non−metals are acidic in natureMetals displace hydrogen from dilute acidsThey can′t replace hydrogen from dilute acidsMetals usually form electrovalent or ionic compoundsNon−metals usually form covalent compoundsThey react with water to form oxides and hydroxides. Some metals react with cold water, some with hot water, and some with steam,depending on their reactivity They do not react with water
