Avange with explanation of the followerion in the increasing order of their- Car, N3, 02,S2, ASsizes? |

Answer» Answer:- (a) Each of the given species (ions) has the same number of electrons (10 electrons). Hence, the given species are isoelectronic, i.eN3- has 7+3 = 10 electronsO2- has 8+2= 10 electronsF- has 9+1 = 10 electronsNa+ has 11-1 = 10 electronsMg2+ has 12-2 = 10 electronsAl3+ has 13-3= 10 electrons (b) The ionic radii of isoelectronic species increases with a decrease in the magnitudes of nuclear charge.The arrangement of the given species in order of their increasing nuclear charge is as follows:N3– < O2– < F– < Na+ < Mg2+ < Al3+Nuclear charge = +7 +8 +9 +11 +12 +13Therefore, the arrangement of the given species in order of their increasing ionic radii is as follows:Al3+ < Mg2+ < Na+ < F– < O2– < N3– very nice handwriting |
