(a) ionic or electrovalent
F is metal and H is non metal.
b) (i) J atomic radius decrease a long a period from left to right nuclear change attraction
increase positive nuclear change increase due to increase in the number of protons.
(ii) F has a smaller atomic radius than N level down the grown.
c) W is group 5 period 3
d) Transition metals.
e) J has 3 valence electrons which and delocalized whole Q has only 2 electron : hence J
has high electrical conductivity due to high number of delocalized electron.
f) The reactions have both metallic and non metal properties
g) H is more reactive than M non metal reactivity increase up the group due to decrease in electro negativity down the group.

- Sodium metal tarnishes when exposed to the air where a white powder is formed on its
surface. A small piece of this sodium metal was dropped...(Solved)
Sodium metal tarnishes when exposed to the air where a white powder is formed on its
surface. A small piece of this sodium metal was dropped into 25g of ethanol and 1200cm3
of hydrogen gas was evolved at r.t.p. The unreacted ethanol was evaporated and a white
solid remained. (Na=23, molar gas volume at r.t.p = 24dm3, C=12, O =16, H=1)
(a) Write a chemical equation for the reaction between ethanol and sodium metal
(b) Determine the mass of sodium that reacted with ethanol
(c) What mass of ethanol evaporated?
(d) The ethanol was evaporated at 80oC, while the white solid remained unaffected at this
temperature. What is the difference in structure of ethanol and the white solid?
(II) (a) Name an inorganic liquid which liberates hydrogen gas with sodium metal
(b) What two differences would you observe if similar pieces of sodium were dropped
separately into small beakers containing equal amount of ethanol and the liquid
named in (II)(a) above respectively
