Answer:
3 electrons
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).
