Each isotope has a different number of neutrons.
Number of neutrons = Mass number of an isotope - 91
Protactinium has 91 protons and electrons; the number of neutrons is different for each isotope: Number of neutrons = Atomic Mass of the isotope - 91
Protactinium has 91 electrons; the valence is 4 or 5.

Protactinium has 91 protons.
Thorium has an atomic number of 90, or in other words, 90 protons in its nucleus. The mass number or the identification of the -232 isotope with its 142 neutrons is a red herring - in isotopy the number of neutrons may vary but the atomic number or the count of protons is the same. If the atomic number varied from 90 it would by definition no longer be thorium.
Protons, neutrons, electrons, and their smaller subatomic particles also, just like any other atom.
Protium has 0 neutrons, Deuterium has 1 neutron, and Tritium has 2 neutrons. Hope it helps!!!! Maria Jaramillo
