The answer is -3. it would have a negative charge to gain
The B. atomic mass of an atom is based on the mass of an atom of carbon-12.
The <em>ionic charge</em> depends on the number of <em>electrons</em>.
The <em>atomic number</em> depends on the number of <em>protons</em>.
<em>Isotopes</em> depend on the number of <em>neutrons</em>.
Electrons, everything is pretty much based around the likeliness of electrons to be swapped or shared between atoms
Here is the answer. I am not sure how to explain it! Sorry!
