Isoelectronic means having the same amount of electrons, so Kr is isoelectric with Br.
When bromine reacts to form an ion, it becomes isoelectronic with krypton. Both bromine (Br) and krypton (Kr) have 36 electrons in their neutral state. When bromine gains one electron to form the Br- ion, it now also has 36 electrons like krypton.
c. Rb plus. Kr has 36 electrons, the same as Se2-, As3+, Sr2+, and Br-. Rb plus has 35 electrons, which is not isoelectronic with Kr.
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.
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.

Neon is isoelectronic with the sodium ion.
Argon is isoelectronic with the sulfide ion.
Hydroxide and water are isoelectronic with fluoride as they have the same number of electrons.
None. The Se2- ion is isoelectronic with Krypton.
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.
