how do you find the mass number, protons, neutrons, electrons, and electrical charge in chemistry?
I'm taking chemistry, and I didn't understand how my teacher found the mass number, protons, neutrons, electrons, or electrical charge. Because I'm home schooled, I can't ask him and I'm not sure if my mom gets it either. So, if you could please help me, that would be great. =)
