Aneutral atom has an atomic number of 20 and a mass number of 41; how many protons, neutrons, and electrons are found within the atom? (2 points) 21 protons, 21 electrons, and 20 neutrons 20 protons, 20 electrons, and 21 neutrons 21 protons, 20 electrons, and 20 neutrons 41 protons, 41 electrons, and 20 neutrons

Well, it's been quite a while since I've done this, and i might be a little rusty so you might just want to double check, but chemistry in a way is kind of basically common sense in a way, so if your atom is neutral and you need to determine the protons, neutrons, and electrons, I would say that you need to calculate and find the one that would most likely, or is neutral. I don't know if this will be of much help, but as of right now it's the best that i can do.
