Question

1.      Which ion of nitrogen, N3+, N3-, N, N2-, and N5+ is the largest?

​

Answer 1

sequence of increasing oder N5+,N3+,N,N2-,N3-

Answer 2

Among the given ions of Nitrogen, N3- is the largest.

• Ions are charged species which may have a positive (cation) or negative charge (anion).
• Cations are formed due to loss of electrons and hence they are smaller in size than the parent atom.
• While anions are formed due to gain of electrons and hence they are larger in size than the parent atom.
• The order of increasing size of given species is: N5+, N3+, N, N2-, N3-
