i) G, H, L: This is because they have 1,2,2 electrons respectively in outer energy level
ii) HK
iii) J has strong covalent bonds and giant atomic structure, while K has weak Van der Waal’s between
molecules due to its simple molecule structure
iv) +4
v) I. Melting point of fluoride of G is higher because fluorine is more reactive than chlorine hence
forms stronger ionic bonds with G than chlorine.
II. reactivity of L is higher. This is because reactivity within metallic group increases down the group
and L is below H, hence looses electrons easily.
