The number of neutrons is the difference between the Atomic Mass of an isotope and the atomic number. Actinium has a great number of isotopes, each with a different mass or number of neutrons.
What else can I help you with?
Mass number of actinium?
Unable to answer without knowing the specific isotope. However I will assume you mean actinium-227 as it is the only isotope with a halflife longer than a few days.227 protons and neutrons each composed of 3 quarks, total 681 quarks89 electronsThis gives a total of either 316 electrons, protons, and neutrons or 770 electrons and quarks. However this does not count the undeterminable number of virtual photons, muons, and gluons being exchanged by those electrons, protons, neutrons, and quarks to couple the electromagnetic, weak, and strong forces between them.
