1 electron

Answer 1

i literally just had a test on this and now i forgot all the work. dam.

Answer 2

3 electrons

Step-by-step explanation:

# of Protons = # of Electrons

UNLESS it is an ion in which case it can have a net charge of +1 (2 electrons) or -1 (4 electrons).

So, your best answer is 3, but if it is an ion, your answer could also be 2 electrons (if it is a positive ion)... or your answer could be 4 (if it is a negative ion).

I hope this helps! <3
