Metal
			Non-metal
		
		
			Metals are electropositive.
			Non-metals are electronegative.
		
		
			
			They react with oxygen to form basic oxides.

			$4 Na + O _{2} \longrightarrow 2 Na _{2} O$

			These have ionic bonds.
			
			
			They react with oxygen to form acidic or neutral oxides.

			$C + O _{2} \longrightarrow CO _{2}$

			These have covalent bonds.
			
		
		
			
			They react with water to form oxides and hydroxides. Some metals react with cold water, some with hot water, and some with steam.

			$2 Na +2 H _{2} O \longrightarrow 2 NaOH + H _{2} \uparrow$
			
			They do not react with water.
		
		
			
			They react with dilute acids to form a salt and evolve hydrogen gas. However, $Cu ,\, Ag ,\, Au , \,Pt ,\,Hg$ do not react.

			$2 Na +2 HCl \longrightarrow 2 NaCl + H _{2} \uparrow$
			
			They do not react with dilute acids. These are not capable of replacing hydrogen.
		
		
			
			They react with the salt solution of metals. Depending on their reactivity, displacement reaction can occur.

			$CuSO _{4}+ Zn \longrightarrow ZnSO _{4}+ Cu$
			
			These react with the salt solution of non-metals.
		
		
			
			They act as reducing agents (as they can easily lose electrons).

			$Na \longrightarrow Na ^{+}+ e ^{-}$
			
			
			These act as oxidising agents (as they can gain electrons).

			$Cl _{2}+2 e ^{-} \longrightarrow 2 Cl ^{-}$
