Question

For the nuclide Na-23 (Z = 11), the numbers of protons, neutrons and electrons inside the nucleus, respectively, are:

G1 Physics · Accepted Answer

Nuclear protons = Z = 11; nuclear neutrons = A − Z = 23 − 11 = 12. Electrons are outside the nucleus, so electrons inside the nucleus = 0. Final answer: Option A (11, 12, 0).
