Thread: Ion = #p-#e-

Find the following electron, proton, neuron of Mg<sup>2+


2 = 12 - #e-

-e = 12-2 =10

Protons 12
Electrons 10
Um Neurons How do I get that...Can someone help</sup>

Sure it's not neutrons? If neutrons should be 12

oops working on 25 hours straight

Atomic weight = proton + neutrons btw so if you have the proton number which I see you do, it should be easy

well that is what I came up with when I subtracted atomic number and atomic mass, so I guess it is right
thx a bunch

Yup I edited my previous post showing how to get it :d

I don't know and I can't understand it.
