Protactinium has 91 electrons; the valence is 4 or 5.
Protactinium is present in trace amounts in nature and can be found in uranium ores. It is used in research as a neutron source and is also studied for its potential applications in nuclear reactors and accelerators. Protactinium has no significant commercial uses due to its scarcity and radioactivity.
Protactinium is primarily used in research applications for its radioactive properties. It can be used as a neutron source and in some nuclear reactions. Its most important isotope, Protactinium-231, is used in dating marine sediments and determining geological ages.
1 neutron It has in its nucleus 1 neutron and 2 protons so its mass number is 3, hence whay it is called helium-3. (Mass number = # of protons + # of neutrons)
The neutral or no charge particle in an atom is called a neutron. Neutrons are located in the nucleus, along with protons. Neutrons have the same mass as protons.
Technically they are two totally different particles. That being said, in beta emission a neutron is converted into a proton and an electron is released.
Uranium-234 become protactinium by emission of a beta particle. A proton is transformed in a neutron.
Protactinium has 91 protons.
Protactinium has 91 protons.
Protactinium has 91 protons and electrons; the number of neutrons is different for each isotope: Number of neutrons = Atomic Mass of the isotope - 91

None. Protons and electrons are not constituents of a neutron. Both neutrons and protons are constituents of an atom's nucleus (core), while the electrons are situated in the electronic cloud around the nucleus.
3He has 2 protons, 1 neutron, and 2 electrons.
If an atom of thorium loses 2 protons, it would turn into an atom of protactinium. Thorium has an atomic number of 90, so losing 2 protons would change it to an atomic number of 88, which is protactinium.
