What are isoelectronic ions? Account for the decrease in size of following species oxide ion > Fluoride ion > sodium ion > magnesium ion.
The ions having same number of electrons are called isoelectronic ions. The above order is due to increasing order of effective nuclear charge.

Ammonia forms the complex ion [Cu(NH3)4]^2+ with copper ions in alkaline solutions but not in acidic solutions. What is the reason for it?
(b) : In acidic solution, NH3 forms a bond with H+ to give NH4+ ion which does not have a lone pair on N atom. Hence it cannot act as...
