ON bombarding uranium with neutrons, Fermi and collaborators 1 found that at least four radioactive substances were produced, to two of which atomic numbers larger than 92 were ascribed.

These captured neutrons were then converted into positively charged protons and thus transformed the uranium into the incrementally larger elements on the periodic table of elements — the so ...

Protons are positively charged ... but before the neutrons can collide with fresh uranium nuclei, they need to be slowed down.

The isotope uranium-238 is typically considered to be the heaviest element found in the natural world. It’s atomic mass is 238 – 92 protons and 146 neutrons. Every other element with a higher ...

As each uranium atom breaks apart ... water and of isotopes—atoms of an element that have the same number of protons but a different number of neutrons and, therefore, different weights.

Because fluorine is essential for converting uranium into a form suitable for ... forms of a chemical element having the same ...
