Answer 11: (d)   Answer 12: (b)   Answer 13: (a)   Answer 14: (b)   Answer 15:(c)   Answer 16:(b)     Answer 17: (b) Hint: Down the group the effective nuclear charge remains almost constant. But down the group with increasing atomic number the number of atomic orbits increases and there by atomic size increases. As a result, the distance of valence shell electron from nucleus increases and attraction between them decreases and therefore ionization energy decreases.

Answer 18: (b)   Answer 19: (a) Hint: CO is neutral towards litmus. SnO₂ and ZnO are amphoteric as they form salts and water with acids and bases. SiO₂ is acidic as it forms salts with bases.

SiO₂ + 2NaOH → Na₂SiO₃ + H₂O.

Answer 20: (a) Hint: The metallic character of the elements is highest at the extremely left (low ionisation energies) and then decreases across the period from left to right (ionisation energies increases across the period)
