Options are not given in the question. But the following species will have the same electronic configuration as Br- ion:
Neutral atom: Kr
Cations: Rb+, Sr2+
Anion: Se2-
Cl- and Ca2+ has the electronic configuration of the noble gas, Ar, with 18 electrons.
All nickel atoms and ions share the same atomic number, which is 28, meaning they all have 28 protons in their nuclei. This characteristic defines them as nickel, regardless of whether they are neutral atoms or charged ions. Additionally, nickel atoms and ions have similar chemical properties due to their configuration of electrons, particularly in their outer shells, which influences their reactivity and bonding behavior.
The stable ions of all the elements except the Transition metals, Actinide, and Lanthanide series (that is the d and f block elements) form stable ions that are isoelectronic to a nobel gas by gaining or losing electrons in order to achieve an s2 p6 stable octet. For example, sodium will lose one electron to have the same electron configuration as neon, while nitrogen will gain three electrons to become isoelectronic to neon.
The element that forms a 2+ ion with the same electronic configuration as Ar is Calcium (Ca). When Calcium loses two electrons, it attains the same electronic configuration as argon by having a full outer shell of electrons.
Potassium and chlorine are the only two that can.
Cesium(I), Cs+1 is an iso-electronic ion to Ba2+ and also iodine, I-1 ions and xenon, Xe0 atoms are iso-electronic to Ba2+ ions.They all have the [Xe] electron configuration: [2, 8, 18, 18, 8], 0
Species (atoms or ions) that have the same number of electrons, and the same electron configuration, are called isoelectronic.
Cl- and Ca2+ has the electronic configuration of the noble gas, Ar, with 18 electrons.
since not all atoms have same no.of electronic configuration they try to attain an octet sharing electrons each other
Generally (but not always) stable ions will have the same the electronic configuration as that of noble gases (completely filled valence shells / orbitals)
Ions are electrically charged particles formed when atoms lose or gain electrons. They have the same electronic structures as noble gases. Metal atoms form positive ions, while non-metal atoms form negativeions. The strong electrostatic forces of attraction between oppositely charged ions are called ionic bonds
The negative ion F has the same electronic configuration as the positive ion Ne. This is because the negative ion F gains an electron to achieve a stable octet configuration, similar to the stable electronic configuration of the noble gas Ne.

Answering by example: Cl- ion, Ar atom, K+ and Ca2+ ions are all 'iso-electronic' to each other, because they all have the same 20 electrons in the same (noble gas) electron configuration (structure) as argon has: [Ar] = [1s2, 2s2 2p6, 3s2 3p6]
