ISOELECTRIC
Structure of atom of Class 9
ISOELECTRIC
Ion or atom or molecule which have the same number of electrons are called as isoelectronic species.
e.g. Cl- Ar K+ Ca+2
No. of electrons 18 18 18 18
Isobars contain different number of electrons, protons and neutrons.
Ex. 1 Which of the following pair are isoelctronic
Co32- and No2- (b) NH3, H2O (c) PCl5, PO32- (d) none of these
Solution: (a) and (b) (for charge calculation see solved example-23)
