What noble gas is isoelectronic with Calcium?

Answer 1

If you go backwards two elements, you will find Neon (Ne). If you go forwards six, you will find Argon (Ar).

Answer 2

Krypton is the noble gas that is isoelectronic with Calcium. Both elements have 20 electrons, with Calcium having the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 and Krypton having the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10.

Answer 3

Mg2+ ion and the noble gas, neon are isoelectronic

Answer 4

Calcium is not isoelectronic with any noble gas. Ca2+ ion is isoelectronic with argon (with 18 electrons).

Answer 5

There is no noble gas that has the the same electron arrangement as Mg- ion. However Mg2+ ion and the noble gas neon (Ne) are isoelectronic

Answer 6

Ba2+ has the same electron configuration as Xenon, Xe

Answer 7

Mg2+ and the noble gas neon, both have 10 electrons. Hence both of them have the same electronic configuration.

Answer 8

Ne

(Neon)

Answer 9

neon

Answer 10

[Ne] 3s2
