Both ions Mg2+ and Al3+ and atoms of Ne are isoelectronic with Na+:
They all have [Ne] 3s0 = 1s2, 2s2 2p6, 3s0

The common d-block ion that is isoelectronic with Zn^2+ is Cu^+. Both ions have the same number of electrons, specifically 28.
The ion that carries two negative charges and is isoelectronic with K+ is O2-. Both ions have 18 electrons, but O2- has gained two electrons to achieve a full outer shell, giving it a total charge of -2.
Chlorine needs only one additional electron to form an ion that is isoelectronic with an atom of the noble gas argon, while sulfur needs two additional electrons to form an ion that is isoelectronic with an atom of the noble gas argon. Ions that are isoelectronic with noble gas atoms are particular stable; therefore, their formation is favored.
The formula of the compound containing Na+ and PO43- ions is Na3PO4. This is because the charges of the sodium ion (Na+) and the phosphate ion (PO43-) balance out when three sodium ions combine with one phosphate ion.

The Sulfide ion, S2-, is isoelectronic with Cl-
The common d-block ion that is isoelectronic with Zn^2+ is Cu^+. Both ions have the same number of electrons, specifically 28.
Mg2+ and neon are isoelectronic
Atoms or ions that have the same number of electrons as helium (2 electrons) are considered isoelectronic with helium. Examples of species that are isoelectronic with helium include H+, Li+, Be2+, and B3+.
The ion that carries two negative charges and is isoelectronic with K+ is O2-. Both ions have 18 electrons, but O2- has gained two electrons to achieve a full outer shell, giving it a total charge of -2.

(Ar) Argon because Ca ion is Ca2+ so it give away 2 electrons
the atomic no of calcium is 20 so to reach the nearest noble gas electronic configuration it loses 2 electrons and forms + 2 ion.
Sulfur forms a -2 ion in an attempt to achieve a complete electron shell that is isoelectronic with Argon. In order to achieve a full 3p shell, Sulfur must gain 2 electrons, becoming a -2 ion.
The ion MnO4 is reduced toMnO2 and sulfur is oxidized to ion sulfate. Sulfite is the reducing agent.
Absolutely not. Magnesium is magnesium, whether it's an ion or not. So it must have 12 protons. The number of electrons, however, is different. Neutral (non-ionic) magnesium has 12 electrons; the magnesium ion (Mg+2) has 10 electrons, which means it is isoelectronic with neon.
