(A)     Metal  Non-metal   Metals are electropositive. Non-metals are electronegative.   They react with oxygen to form basic oxides. $4Na + O_2 \longrightarrow 2Na_2O$. These typically form ionic bonds. They react with oxygen to form acidic or neutral oxides. $C + O_2 \longrightarrow CO_2$. These typically form covalent bonds.   They react with water to form oxides or hydroxides and hydrogen gas. $2Na + 2H_2O \longrightarrow 2NaOH + H_2 \uparrow$. They generally do not react with water.   They react with dilute acids to form salt and hydrogen gas. $2Na + 2HCl \longrightarrow 2NaCl + H_2 \uparrow$. They do not react with dilute acids as they cannot displace hydrogen.   They act as reducing agents because they easily lose electrons. $Na \longrightarrow Na^+ + e^-$. They act as oxidizing agents because they gain electrons. $Cl_2 + 2e^- \longrightarrow 2Cl^-$.

Differentiate between metal and non-metal on the basis of their chemical properties.
