It is not clear what "greater" means. In terms of atomic number (number of protons in the nucleus) there is not even an element which is twice as great.
Transuranium elements are those that have an atomic number greater than uranium's, which is 92. The first transuranium element is neptunium (Np) with atomic number 93.
Polonium is more toxic and has a specific radioactivity greater than uranium but cannot be used in nuclear weapons.
More electrons, protons, neutrons and a greater atomic weight.
No, plutonium is a different element entirely.
Uranium is a radioactive element; uranium is also a toxic element. But the nuclear energy based on uranium is cleaner than the energy based on coal or oil.
Transuranium elements are those that have an atomic number greater than uranium's, which is 92. The first transuranium element is neptunium (Np) with atomic number 93.
Just like hundreds are greater than tens, hundreds of thousands is larger than tens of thousands.
Uranium is more dense than lead, yes. The density of the two metals is 19.1 and 11.34 grams per cubic centimeter, respectively. That makes uranium almost twice as dense as lead.
greater than what
Uranium is an element and therefore by definition contains no chemical other than itself.
Boron is lighter than carbon and uranium.
Uranium, U is.
