An atom has an 16 protons, 18 neutrons, and 13 electrons. what are its atomic number, atomic mass, and net charge?
a) atomic number = 16, atomic mass = 34, net charge = 3+
b) atomic number = 16, atomic mass = 34, net charge = 3−
c) atomic number = 34, atomic mass = 16, net charge = 3+
d) atomic number = 34, atomic mass = 16, net charge = 3−
