What is mean by isoelectronic species?
What is mean by isoelectronic species?
Answer: Isoelectronic species are known as atoms or ions that have the same number of electrons. In isoelectronic species, there the number of electrons would be equal but the elements would be different. In other words, ions and atoms which are having equal numbers of electrons are called the isoelectronic species.
What are isoelectronic species explain with example?
Isoelectronic species refers to the species which have same number of electrons. For e.g. CO and N2 are isoelectronic as both have same number of electrons i.e. 14.
Which is the isoelectronic pair?
– Isoelectronic pairs are those pairs of atoms, ions or molecules that have the same number of electrons in them. – For finding the isoelectronic pairs, we can just add the number of electrons of each atom in the species and also the charge of the species (if present).
Which group has isoelectronic species?
O2– , F–, Na+ , Mg.
Which of the following are isoelectronic and isostructural?
NO-3,CO2-3,ClO-3,SO3. Solution : NO-3 and CO2-3 both have same number of electrons (equal to 32) and central atom in each being sp2 hybridised, planar are isostructural too. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.
Which one of the following sets of ions represents the collection of isoelectronic species?
N and Kr3+.
Which of the following is not paramagnetic?
And S2− has no unpaired electron in its MO’s, so, it is diamagnetic.
Is Zn paramagnetic?
Answer and Explanation: Zinc is diamagnetic. Substances that are diamagnetic are weakly repelled by a magnetic field.
Is O2 minus is paramagnetic?
O2, O2− and O2+ all are paramagnetic.
Is co paramagnetic or diamagnetic?
CO is diamagnetic because all of its electrons are paired.
Is 02 paramagnetic or diamagnetic?
Ernest Z. O2 is paramagnetic because it has two unpaired electrons.
Is Mn 2 paramagnetic or diamagnetic?
Mn2+ has 5 unpaired electrons therefore it is paramagnetic.
Is MN paramagnetic or diamagnetic in ground state?
Its stable form ) – yes, it is paramagnetic not ferromagnetic, so just changing the crystal slightly. Of manganese, oxygen, platinum, alkali and alkaline earth metals molecules, not atoms paramagnetic!
Why is 02 paramagnetic?
Why is O2 paramagnetic? According to molecular orbital Theory (MOT), there is 1 unpaired electron in the π2px antibonding orbital and another unpaired electron in π2py antibonding orbital. As molecules containing unpaired electrons are strongly attracted by magnetic field, hence oxygen has paramagnetic nature.
Which form of oxygen is diamagnetic?
O22- is known to be diamagnetic. This is because there are no unpaired electrons in O22-.
How does oxygen support the MO model?
The presence of two unpaired electrons has proved to be difficult to explain using Lewis structures, but the molecular orbital theory explains it quite well. In fact, the unpaired electrons of the oxygen molecule provide a strong piece of support for the molecular orbital theory.
Is O2 more stable than O2+?
1 Answer. O2+ is more stable than O2-. Because According to molecular orbital theory O2+ has 15 electrons &it has one electron in antibonding orbital. In the case of O2- 17 electrons are present &3 electrons are present in antibonding orbitals.
Is f22+ paramagnetic or diamagnetic?
F₂²⁺ is paramagnetic. Total number of electron present in F₂²⁺ is equal to 16 (i.e, 9+9-2). From the molecular orbital electronic configuration, number of electrons present in pi orbitals present is equal to 2. So, F₂²⁺ is paramagnetic.
What is the bond order of F2 2+?
1/2
How do you find the bond order?
If there are more than two atoms in the molecule, follow these steps to determine the bond order:
- Draw the Lewis structure.
- Count the total number of bonds.
- Count the number of bond groups between individual atoms.
- Divide the number of bonds between atoms by the total number of bond groups in the molecule.
