The only elements that form an ion isoelectric with krypton are the elements in Period 4 and Columns 15 through 17 of a wide form Periodic Table and the elements in Period 5 and Columns 1 and 2 of a wide form periodic table. All other elements do not form such an ion.
No, argon does not form an ion isoelectronic with krypton. Argon has 18 electrons, while krypton has 36 electrons. To be isoelectronic, the two species should have the same number of electrons.
None. The Se2- ion is isoelectronic with Krypton.
Krypton and selenide ion are isoelectronic with 36 electrons each
Argon is isoelectronic with the sulfide ion.
S2- ion is isoelectronic with argon (with 18 electrons).
Atoms are isoelectronic when they have the same electron configuration. Therefore, an anion isoelectronic to krypton is bromide. A cation isoelectronic to krypton is rubidium.
bromide
No, argon does not form an ion isoelectronic with krypton. Argon has 18 electrons, while krypton has 36 electrons. To be isoelectronic, the two species should have the same number of electrons.
None. The Se2- ion is isoelectronic with Krypton.
krypton
No, bromine forms an ion with a charge of -1. An ion isoelectronic with krypton would have the same number of electrons as krypton, which is 36 electrons.
Krypton and selenide ion are isoelectronic with 36 electrons each
Argon is isoelectronic with the sulfide ion.
Krypton, calcium, chlorine+1 are isoelectronic with argon because they all have the same number of electrons, 18.
Krypton, radon, and xenon cation are all isoelectronic with xenon because they have the same number of electrons.
Krypton is the noble gas isoelectronic with calcium, meaning they have the same number of electrons.
Isoelectronic means having the same amount of electrons, so Kr is isoelectric with Br.
