Isosteres are molecules or ions that have a similar shape and often have similar electronic properties. Isodiaphers are atoms with different atomic number and mass number, but with the same difference between the number of neutrons and the number of protons

Isodiaphers are elements with different ATOMIC NUMBER but same isotopic number ( ie:- no. of neutrons - no. of of protons )
eg :- 92 U 238 and 90 Th 234
Isosters are molecules or ions with same no. of atoms as well as total no. of electrons.
eg:- CO2 and N2O
