Is the electron structure of a Zinc ion and example of a pseudo-noble gas formation?
Yes, the electron structure of a Zinc ion (Zn2+) can be considered an example of pseudo-noble gas formation. When Zinc loses its two valence electrons to become Zn2+, it attains a stable electronic configuration similar to a noble gas (argon) with a completely filled d orbital (3d10) which enhances its stability.
What is ionic zinc?

What common d-block ion is isoelectronic with Zn2?
The common d-block ion that is isoelectronic with Zn^2+ is Cu^+. Both ions have the same number of electrons, specifically 28.
What is the ion formula for zinc?
+2. Zinc forms the Zn2+ ion in its ionic compounds. Zinc has electronic configuration of [Ar] 3d10, 4s2 and the two s electrons are lost to form the Zn2+ ion.
If zinc and iron are used to make a cell what half-reactions will occur for zn2 plus aq plus 2e- zn s e0 equals -0.76 v and for fe3 plus aq plus e- fe2 plus aq e0 equals 0.77 v?
Zn(s) → Zn2+(aq) + 2e- and Fe3+(aq) + e- → Fe2+(aq)
Why the complex of Zn2 plus is white colour?
The white color of Zn2+ complexes is attributed to the fact that Zn2+ lacks partially filled d orbitals for d-d electronic transitions that typically give rise to color in transition metal complexes. As a result, Zn2+ complexes do not absorb visible light in the range that produces color, leading to their white appearance.
Which is the least likely to be reduced zn2 fe3 fe2 cu2?
Fe3 is the least likely to be reduced because it has the highest oxidation state among the listed elements, making it less prone to gaining electrons and being reduced.
What is the chemical formula for the ternary compound composed of Zn2 plus and OH ions?
The chemical formula for the ternary compound composed of Zn2+ and OH- ions is Zn(OH)2.
What is the ion that has 30 protons and 28 electrons?
The number of protons = atomic numberThe number of electrons = atomic number - net ion charge (no charge means not ion)The number of neutrons = mass number - atomic numberAlways start with protons if they are given. If they are not given, use the other numbers to figure out how many protons there are. The 9 protons in this question immediately tell you that the atomic number is 9. This is a dead giveaway as to which element is being discussed. Just look on the periodic table for the atomic number of 9, which is... Flourine! The number of electrons will tell you whether this is an ion or not. Ions are not stable (neutral). This means that they have a negative or positive charge. If you know how to draw a shell diagram, you can place the electrons. If all shells are filled completely and there are no extra electrons in unfilled outer shell, then it is not an ion.
What is zincs charge?
Zinc typically forms a +2 charge when it loses electrons to achieve a stable electron configuration.
