Question

What do you mean by isoelectronic species? Arrange the following isoelectronic species in increasing
order of their atomic/radius.
F-, Si4+, C4-, Ne, N3-, Mg2+

Answer 1

Answer:

ISOELECTRONIC SPECIES

are those who have the same no of electrons.

for isoelctronic species

the atomic radius inversly proportional to the Atomic no.

hence Si < Mg< F< N< C < Ne as noble gases have highest radius
