प्रश्न
Arrange the following in increasing order of property indicated
I, I+, I- (atomic size)
उत्तर
I+ < I < I-
Size of a cation is always smaller than the corresponding atom due to decrease in number of electrons and increase in effective nuclear charge i.e., greater force of attraction by the nucleus on the electrons.
Size of an anion is always more than the corresponding atom due to decrease in effective nuclear charge i.e., lesser force of attraction by the nucleus o the electrons.
