How many electrons does uranium 237 have?
A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons.
How many neutrons does uranium 237 have?
They artificially produced 231Th, a member of the natural actinium series of nuclides, by bombarding thorium with fast neutrons. This resulted in the discovery of 237U, a new isotope of uranium, by bombarding uranium with fast neutrons, and confirmed that 237U disintegrates into element 93 with a mass number of 237.

How is neptunium-237 formed?
Trace amounts of the neptunium isotopes neptunium-237 and -239 are found naturally as decay products from transmutation reactions in uranium ores. In particular, 239Np and 237Np are the most common of these isotopes; they are directly formed from neutron capture by uranium-238 atoms.
Is neptunium-237 radioactive?
… are radioactive; the stablest is neptunium-237, with a half-life of 2,144,000 years, and among the most unstable is neptunium-225, with a half-life of more than 2 microseconds. Neptunium-237 can be separated from used reactor fuel to study the physical and chemical properties of the element.
