Scientists say that most of the mass of an atom is located in the nucleus because protons and neutrons are located in the nucleus, and electrons are outside the nucleus. Since an electron has A. Almost zero
B. A large

I believe the answer is "A. almost zero."

Even though you haven't put the rest of the question, I assume it asks what the "weight" of an electron is in comparison to neutrons and protons.
