Question

isoelectronic species of oxide ion​

Answer 1

Answer:

Isoelectronic species are species with same number of electrons. Oxygen ( O, Z=8) has electrons but oxide ion ( O2-) with addition of 2 electrons has 10 electrons. In order to be isoelectronic with oxide ion (O2-) the specie should have 10 electrons

Answer 2

Isoelectronic species of oxide ion​ are $\[N{{a}^{+}},{{F}^{-}},M{{g}^{2+}},{{N}^{3-}}\]$ etc.

Explanation:

• Isoelectronic species are the species with same number of electrons,but their atomic number will be different.
• Oxide ion is an anion and it is divalent.
• It can be represented as $\[{{O}^{2-}}\]$ ion.

• The number of electrons present in oxide ion  $=8+2=10$

• So the species that have ten electrons in them will be isoelectronic with oxide ion.
• Examples of such species are,$\[N{{a}^{+}},{{F}^{-}},M{{g}^{2+}},{{N}^{3-}}\]$ etc.
