The Isoelectronic concept is used to describes dissimilar atoms or ions with identical electronic configurations. They must have Atomic Mass greater then hydrogen, the same number of nuclei and the same number of electrons.
Neon is isoelectronic with the sodium ion.
Argon is isoelectronic with the sulfide ion.
None. The Se2- ion is isoelectronic with Krypton.
Hydroxide and water are isoelectronic with fluoride as they have the same number of electrons.
Krypton, calcium, chlorine+1 are isoelectronic with argon because they all have the same number of electrons, 18.
The noble gas that is isoelectronic with S2- is Argon. Both S2- and Argon have 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.
An atom is isoelectronic with another if they have the same number of electrons. The neutral atom that is isoelectronic with F (9 electrons) is Ne (neon). For Ca²⁺ (20 electrons), the isoelectronic atom is Ar (argon). P³⁻ (18 electrons) is isoelectronic with Ar as well, while K⁺ (18 electrons) is also isoelectronic with Ar. Pb²⁺ (78 electrons) is isoelectronic with the neutral atom Xe (xenon).
The noble gas neon (Ne), is isoelectronic with N3- ion (not N atom)
Nitrogen is isoelectronic with oxygen, as they both have the same number of electrons, which is 8.
Oxide ion (O2-) is isoelectronic with neon. Both species have the same number of electrons, which is 10.
Yes, the molar mass is different for isoelectronic molecules.
