Question

An atom has an 16 protons, 18 neutrons, and 13 electrons. What are its atomic number, atomic mass, and net charge?

atomic number = 16, atomic mass = 34, net charge = 3+
atomic number = 16, atomic mass = 34, net charge = 3−
atomic number = 34, atomic mass = 16, net charge = 3+
atomic number = 34, atomic mass = 16, net charge = 3−
