Answer: The mass is eleven with a negative 3 charge

Explanation:

Add the protons and neutrons. This makes 11. In a stable molecule, the protons and electrons would have the same number, but this is not a stable molecule, so subtract the number of protons from the number of electrons. this makes your negative charge. Electrons are not counted when calculating molecular mass.
