What are isoelectronic species?
What are 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 give one example?
Isoelectronic species are elements or ions that have the equal number of electrons. Example: O2−,F−,Mg2+ have 10 electrons.
How do you identify an isoelectronic species?
– 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). – Then, if the number of electrons are equal in both species, they are said to be isoelectronic pairs.
What is isoelectronic with O2?
Answer: The neutral atom which is isoelectronic with O2 is sulfur (S). Explanation: Atomic number of oxygen is 8.
Which ion is isoelectronic with CO?
Isoelectronic species are having same number of electrons . Hence, CO isoelectronic with CN- ion.
Which of following pair is Isoelectronic?
Solution : BrO-2 and BrF+2 ions are isoelectronic in nature.
Which pair is isoelectronic and isostructural?
With this we will determine the number of electrons in the valence shell and its structure based on the valence bond theory. From the above explanation we can conclude that the pair of isoelectronic and isostructural species is ClO−3, SO2−3.
How IBr2 and XeF2 are isoelectronic?
NEET 2017 How can [IBr2]- and XeF2 be isoelectronic? Since valence shell electrons is same so they are isoelectronic.
Which pair gives cl2 at room temperature?
HNO3
Which pair gives at room temperature?
HCl ( conc.) and KMnO4 is the pairs of substances when mixed, produces chlorine gas at room temperature.
What is the only non metal which is liquid at room temperature?
bromine
What is br2 room temperature?
Bromine (Br, element 35), also found as a diatomic molecule (Br2), is a liquid at room temperature, solidifying at -7.2ºC….Physical States — Melting Points, Boiling Points, and Densities.

Why is f2 a gas?
In fluorine, the electrons are tightly held to the nuclei. The electrons have little chance to wander to one side of the molecule, so the London dispersion forces are relatively weak. At a low enough temperature the molecules will all be solids. At a high enough temperature they will all be gases.
