Does this question work? Quantum Physics
Hey guys,
This question is a part of my homework:
The Carbon (14 nucleons, 6 proton no. ) loses two electrons. It forms the ion Cu^2+ . For the ion formed;
(i) calculate its charge in C
is -3.2*10^-19 C correct?
(ii) state the number of nucleons it contains,
is 14 correct?
(iii) Calculate the mass in kg of the ion
is 2.338*10^-26 correct?
My worry is that the question states "for the ion formed" but I was not given any other details about Cu. Or, am I supposed to use a periodic table?

1) No. If it loses two electrons it will be positively charged.
It may help if you give the whole question rather than part of it.

What I posted was part (b) part (a) is below:
How many protons, neutrons and electrons are there in an atom of Carbon (14 nucleon no. 6 proton no.)
............................... protons
............................... neutrons
............................... electrons
I put 6, 8, 8 respectively.
Does it help?

Should be 6,8,6 respectively, no? At least for a stable atom.

Yeah sorry, typo :/

I think OP is correct for part 1. The Q is asking for the change (delta), not the result in the ion.

What is OP ? ^^ Sorry

No the question asks for the charge on the ion after losing 2 electrons. Not the change.

Oh Gosh yeah. My bad! :P

OP means Original Poster
As in, the guy who started the threadSo do I work with Carbon (14 nucleon, 6 proton no. ) ^2+ ?

I'd assume so.

I might be missing something...how does a carbon atom change into a copper atom by losing 2 electrons?
It can't. Is there a misprint in your original question? For Cu read C?
It looked like the original question was about carbon simply losing 2 outer electrons to become a carbon 2+ ion.
If it loses two beta particles (electrons) from the nucleus it becomes oxygen, which has 8 protons. Carbon has 6. The process increases the number of protons by 2 by converting 2 neutrons to protons.
Can you post the original question in its entirety.
This confusion always occurs when part questions or poster's paraphrases of questions are posted.

Yeah, so I think this is why the OP is confused - he was saying there is no information given about Cu.
Hey there,
Sorry no scanner available :/
It just gives me C(14 nucleons 6 protons), which loses two electrons which forms then to an ion of Cu^2+.
Could be a misprint, I think the school created these questions :/

Managed to get a photo.
P.S. The white marks are Tippex.

The question is nonsense.
A C atom cannot become a Cu2+ ion by losing 2 electrons.
It would become a C2+ ion.
Or maybe it should hve been a Cu atom becomes Cu2+
So it's either C or Cu but it can't be both.
The number of protons and neutrons doesn't change as a result of losing those two electrons.

Hmm I see, do you think my working solution should get marks? Stupid school... _._
I leave it to the marker to determine how many marks you get.
But, yes
That carbon atom does have
14 nucleons
6 protons
8 neutrons
Yes, after losing the 2 electrons and becoming an ion it has an overall charge of + 3.2 x 10-19C
You need to say how you calculated the mass of the ion.
It's not clear from the question what data you are supposed to assume.
