There doesn't seem to be much info on the internet around this, and my chem teacher won't really aid me out. It's early out tommorow, even if someone can't respond before then I would still prefer to know the price sometime. Below it is:Atoms and also ions v the same number of electrons are dubbed iso-electronic. Write a symbol for a cation and also an anion that room iso-electronic v krypton. Is it feasible for a cation to it is in iso-electronic v an anion native the very same period? Explain.If someone could give me a hint or noþeles that would be cool. Thx.

O2-, F-, Na+ and Mg2+.They room all have the same variety of electrons (10), however different variety of protons (8,9,11,12).They space all isoelectronic ions. Girlfriend should have the ability to figure the end which noble gas they space isoelectronic with and go from over there to answer her question.

ok therefore Mg2+ is isoelectronic v Ne right? so if thats appropriate then Se2- and Sr2+ would be isoelectronic with Kr right?
Yes, however make sure you recognize what the subscripts 2+ and also 2- mean. Simply do not follow the exact same pattern ns did since it is a pattern. Make certain you are complying with the pattern since you know what the subscript mean, and what Mg2+ means, etc.
Yea I understand what it means, 2- is adding 2 electrons and 2+ is acquisition away 2 electrons, and Se2- is isoelectronic through krypton due to the fact that they would have the same number of electrons. And also for the second part of the question, "Is it possible for a cation to it is in isoelectronic v an anion indigenous the same period?", It would certainly be feasible right? due to the fact that wouldn't Al- be isoelectronic through P+
And because that the second part of the question, "Is it possible for a cation to be isoelectronic with an anion indigenous the very same period?", It would be feasible right? since wouldn't Al- it is in isoelectronic v P+

This is a hard question, not because it is difficult but because the price is based on what you are taught. Chemistry is typically slowly accumulated on semi-right and wrong principles.So for the example you have actually given, based on the routine trends you have actually learned from her teacher and in your book, is it possible for Aluminum to form a cation and also phosphorus come from one anion?
