    Isosters are those atoms which have similar number of electrons in their valence shell. For example F and Cl. They have 7 electrons each in their outermost shell. In fact every group in Mendeleev's period table represent the members of Isosters group. Isosters could be also from different groups. For example F- is isoster with H-. Isoelectronic species are those atoms/ions having same electron numbers but with different nuclear charges

    In N2 two atoms electrons =7+7=14 and in CO also two atoms...electrons 8+6=14...so they are isosters
