State reason for the following : (i) Non-metals cannot displace hydrogen from the acids. (ii) Hydrogen is not a metal, yet it is placed in the activity series of metals. (iii) Aluminium is more reactive than iron, yet its corrosion is less than that of iron.

1.	State reason for the following : (i) Non-metals cannot displace hydrogen from the acids. (ii) Hydrogen is not a metal, yet it is placed in the activity series of metals. (iii) Aluminium is more reactive than iron, yet its corrosion is less than that of iron.
Answer» Solution :(i) Non-METALS are ELECTRON acceptors, they cannot supply electrons so as to convert `H^(+)` as ion to `H_(2)(g)`. (II) Like metals, hydrogen can lose an electron to form positive `H^(+)` ion. (iii) ALUMINIUM is covered with a strong protective layer of oxide which protects the metals from further corrosion.
