Question

which element would have 2 electrons and +1 charge

which element would have 18 electrons and +3 charge.

Answer 1

I know you didn't expect to get this answer but the answer to both is none. ALL elements have a zero charge. You may want to rephrase your question.

Answer 2

Reworded:

Enter the symbol of the element which would have 18 electrons and +3 charge

and the element with 2 electrons and +1 charge

Answer 3

Another problem. Do you want 18 electrons in the outer shell for the first one or is that 18 electrons total. If total then I would go with Sc (21 total - 3 electrons = 18 and a +3 charge) so Sc^3+.
The second one is Li^+. It has 3 electrons to start and when it loses one that leaves two and a +1 charge.

Answer 4

thanks so much!
