a) K and N because they are in the same group of the periodic table
b) L2O7
OR
L2O
c) L: Because it has 7 electrons in its outmost energy level and so belongs to group (VII)
d) M: because its atomic radius is large so its tendency to donate its electrons is high
e) M and N are in the same period. Across the period, ionic radius decreases due to increase in nuclear
charge, which results in strong attraction of electrons
f) L gains electrons to form L-. Due to increased number of electrons, there’s increased
electron repulsion.
