QESTIONS TO REVISE FOR PANNEL EXAMINATION
Phosphorous and Nitrogen belong to the same group 3. Whereas Nitrogen forms diatomic molecule Phosphorous does not. Give reason/s.
Explain the reactions of group I elements towards water
Define electron affinity. Values of second electron affinities are always positive. Explain
Hydrogen (H2) and Chlorine (Cl2) molecules are non-polar whereas HCl molecules are polar. Give reason/s.
Beryllium chemistry does not display the typical characteristics of group II elements. Discuss
Explain the diagonal periodic relationship of Aluminium and Beryllium
Properties of Lithium compounds are anomalous in relation to other members of group I but resemble those of Magnesium. Explain
Carbon tetrachloride (CCl4) is hydrolyzed whereas Silicon tetrachloride (SiCl4) is rapidly hydrolyzed. Explain
Solubility of hydroxides of group II increases down the group whereas solubility of the sulphates of the same group increases up the group. Give reason/s
Most main group I & II elements dissolves in liquid ammonia giving solutions that are blue and paramagnetic when dilute, the paramagnetism decreases with increasing concentration. Explain
SF6 is resistant to chemical attach, explain the principal factors responsible for this behavior.
Hydrogen does not belong to any group in the periodic table. Give reasons
Explain the periodic trend in atomic and hydration radii of the alkali metal cations.
Define catenation; it is an important feature of which group, explain its trend and reason for the trend within the group.
Ionization energies and atomic radius are inversely proportional. Discuss
The chemistry of hydrogen isâ predominantly covalentâ explain.
With a very high charge density, aluminium would not be expected to exist widely as a free Al+3 ions, yet it does exist in the form of a hydrated Al+3 ions. Explain.
Explain similarities in the chemistry of Boron to that of diagonal related…
