Uranium is a chemical element of atomic number 92, meaning there are 92 electrons orbiting 92 protons and about 143 neutrons. The protons and neutrons make up the center nucleus of an atom, and contributes to almost all the mass of the atom. Uranium is the most massive naturally-found element with 238 atomic mass units.

This atom makes up a lot of Earth’s outermost layer, since it does not mix with the molten iron that sits in the upper mantle. This leaves a highly concentrated mixture of uranium to sit in Earth’s crust. The high mass content of uranium atoms make breaking down uranium very easy, and continually breaking down uranium exerts usable energy, coming from the energy in these chemical bonds. Breaking these chemical bonds can supply nuclear power, and is used in many nuclear power plants across the U.S.

Uranium is an element, so it can't be split into anything smaller without turning it into something else, something that is not uranium. Each atom of uranium is made of several smaller components, like 92 protons, 92 electrons, and likely 146 or 143 neutrons, depending on what type of uranium it is.

Most elements are made of a combination of an atomic core formed of neutral neutrons and positively charged protons, and these are surrounded by a negative cloud of electrons.

Molecules are made of chemical elements, which are made of protons, neutrons, and electrons! Uranium is an element and it is made of 92 protons, 92 electrons and 142 neutrons. Uranium is a silvery-white metal and is used for it’s nuclear properties. It’s currently also used in military tank and vehicle armor because of it’s extreme density and hardness!

Uranium is an element, not a compound. An atom of uranium contains 92 protons, and a different number of neutrons depending on the isotope. Fissionable uranium (that you would have in a bomb) has 143 neutrons, but the more common and less radioactive isotope has 146 neutrons. A neutral atom of uranium will also have 92 electrons, but it is possible to ionize the electrons away just as with any atom.
