Decide if the following are isoelectronic series. If it is an isoelectronic series select True, if not select False.

Al, Si, P, S

Na, Ca, Y, Hf

O2-, S2-, Se2-, Te2-

P3+, P, P5+

Na+, K+, Rb+, Cs+

Be2+, Mg2+, Ca2+, Sr2+

Solutions

Expert Solution

Al, Si, P, S ------ false

Na, Ca, Y, Hf ------ false

O2-, S2-, Se2-, Te2- ------ false

P3+, P, P5+ ------ false

Na+, K+, Rb+, Cs+ ------ false

Be2+, Mg2+, Ca2+, Sr2+ ------ false

Al3+, Mg, Na, Si ------ false

Explanation :

iso electronic species are which is having same number of electrons.

here all are false . because no set has same number of electrons.

for Al, Si, P, S

Al - no .of electrons = 13

si - no .of electrons = 14

P - no .of electrons = 15

S - no .of electrons = 16
