Which one of the following is isoelectronic with Ne?

Which one of the following is isoelectronic with Ne?

Neon has 10 electrons while oxygen has 8 electrons so it gains two electrons forming a anion O2− with 10 electrons and having the same number as neon. Was this answer helpful?

Which is isoelectronic with neon?

fluorine
Here Neon and fluorine are isoelectronic species. Fluorine ion has 10 electrons making it isoelectronic with neon.

Is nitride isoelectronic with neon?

Explanation: The trick here is to realize that the nitride anion, N3− , is isoelectronic with neon, Ne , the noble gas that shares a period with nitrogen, N . In other words, the nitride anion has the same number of electrons as neon.

Is isoelectronic with argon and isoelectronic with neon?

Cl- ion
Explanation: The Cl- ion has 18 electrons and is isoelectronic with argon while the F- ion has 10 electrons making it isoelectronic with neon.

Is sodium and neon isoelectronic?

The sodium ion is isoelectronic with the neon atom.

Which of the following chemical species is not isoelectronic with a neon atom?

So, sodium is not isoelectronic with neon.

Is isoelectronic with argon and?

Answer and Explanation: The species with is isoelectronic with argon is D) Cl− D ) C l − . Argon is a noble gas with the atomic number 18.

Is neon a noble gas?

neon (Ne), chemical element, inert gas of Group 18 (noble gases) of the periodic table, used in electric signs and fluorescent lamps.

Is neon molecular or atomic?

Hence, “neon” is both a molecule and an atom.

Is O2 isoelectronic with neon?

The atomic number of oxygen is eight,that means, the number of electrons in an oxygen atom is eight. In ${{\rm{O}}^{2 – }}$, due to gaining of two electrons the number of electrons is ten. So, ${{\rm{O}}^{2 – }}$is isoelectronic with neon. Hence, option A is correct.

What elements are isoelectronic with argon?

And we can see that the potassium ion, K+, has the same electronic configuration as the chloride ion, Cl-, and the same electronic configuration as an atom of argon, Ar. Therefore, Ar, Cl-, and K+ are said to be isoelectronic species.
