option (ii)
Its tendency to gain a single electron in its valence shell to attain stable electronic configuration.
Like halogens (with ns2np5 configuration belonging to the seventeenth group of the periodic table), it is short by one electron to the corresponding noble gas configuration, helium (ls2).
