JEE Mains · Chemistry · STD 11 - 3. Classification of elements and periodicity in properties

\(N^{3-} , O^{2-}\) અને \(F^-\) ની આયનીય ત્રિજ્યા ( \(\mathop A\limits^o \) માં ) અનુક્રમે નીચેના પૈકી કઈ એક છે ?

  1. A \(1.71, 1.40\) અને \(1.36\)
  2. B \(1.71, 1.36\) અને \(1.40\)
  3. C \(1.36, 1.40\) અને \(1.71\)
  4. D \(1.36, 1.71\) અને \(1.40\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(1.71, 1.40\) અને \(1.36\)

Step-by-step Solution

Detailed explanation

The ionic radii (in \(\dot{A}\) ) of \(N^{3-}, O^{2-}\) and \(F^{-}\) are respectively 1.71,1.40 and \(1.36 .\) \(N^{3-}, O^{2-}\) and \(F^{-}\) contains ten electrons each. Hence, they are isoelectronic species. For isoelectronic species, the nuclear charge increases on moving…
