Question:

Which of the following atoms or ions (N, O, Al, S2-, Zn2-) has 3 unpaired electrons?

Studying for entrance exams to go back to school and my question book only has answers to odd numbered questions, so I need some help confirming answers! Thanks, I will choose best answer!

Answer:

First had to figure out what the hell, is a JRCA rifle firing pistol ammo, well there's your problemThere is nothing right about thatYou need to decide if you want your rifle, or your pistolJust pullin' your chainI have never had a single problem with CCI ammo as you describeIn fact you may have had the same idea in mind as I do oftenI use CCI as a try it out, go to ammo, to look for the first indication of an accurate shooting new handgunThat CCI stuff is a great benchmark I have foundNow, let me say though I use mainly .45 ACPA few hundred 9Mm roundsBut, you may be speaking, as I am thinking of .40 caliberAnd there I have no answers, I own nothing in .40 I would not have been surprised if you were seeing split case mouths with CCIOnly thing that comes to mind, I know Aluminum has a slightly lower melting point then BrassAluminum 1218 Fahrenheit, compared to 1700 for brass( I did have to look up those exact numbers, I do not claim to have that in residence in my mind ya know ) Wonder if you had a really hot barrelThat is all I could think ofOnly you would know if that could be the answerIf I experienced that, I may just have to get on the horn with CCI Monday to learn moreYou know the details.
Not sure what a JRC is Does it work fine with other ammo? Seems like the extractor is not lining up properlyClearly that ammo is not proper for the gunToo many acronyms of which we can not fathomSpell it out to be more clear, please.
Nitrogen has 3 unpaired electrons: 1s2 2s2 2px1 2py1 2pz1 Oxygen has 2 unpaired electrons Aluminium has just one unpaired electron S2- has a total of 18 electrons all of which are paired Zn+2 has total of 28 electrons again all of which are paired
