Is it true that you need to burn 25 railway truckloads of coal to obtain the same amount of energy provided by a piece of uranium the size of a golf ball?
7 g 235U is approx. equivalent to 20 t coal (for the complete fission of the uranium).
How much does a ten pence piece weigh?
The United Kingdom began minting the two penny piece in its current form in 1971. The coin weighs 7.12 grams.
What important discovery did Becquerel make upon examining a piece of pitchblende wrapped up in paper?
Radioactivity, Becquerel concluded uranium emitted radiation without an external source such as the sun.
How much do 5c weigh?

How much uranium is left if a solid piece for one half life?
Half life is the time taken for half the atoms to decay. Whatever mass you start with, if it is a sample consisting of one pure uranium isotope, you will have half that mass of uranium after one half life. The piece of metal will not weigh half of the original mass, because the decay products will be there. In practice, a piece of uranium usually consists of a mixture of isotopes with different half lives.
How much uranium is left if a solid piece exists for one half-life?
Half life is the time taken for half the atoms to decay. Whatever mass you start with, if it is a sample consisting of one pure uranium isotope, you will have half that mass of uranium after one half life. The piece of metal will not weigh half of the original mass, because the decay products will be there. In practice, a piece of uranium usually consists of a mixture of isotopes with different half lives.
Why is it safer to handle a piece of uranium than to breathe in uranium dust?
Because the uranium dust is inhaled and accumulated in the lungs; long term inhalation of uranium (or uranium compounds, also liquid aerosols) can lead to lungs cancer. Handling a piece of uranium with gloves is not dangerous (excepting of course the irradiated uranium; in this case we use hot cells).
When talking about an isotope what piece of information are we concerned with?
When speaking of an isotope, one is concerned with the number of neutrons present in the nucleus.
What is the color if any in solid liquid gas states for uranium?
Uranium is a solid metal; the non-oxydated surface of a uranium piece is lustrous, very similar with the aspect of steels.
What weighs a milligram?
A piece of gum.
How are an atom an element and an isotope different from each other?
An element is a class of substances An atom is the smallest possible piece of an element. An isotope is an electrically charged atom.

Why is a person's body after it died called remains not remain?
Because there is more than one piece-remain(s)
Are elements such as Plutonium and Uranium more reactive than Francium?
It's important to note that plutonium and uranium (element names are not normally capitalized in the middle of a sentence) have isotopes which are stable enough that their reactivity is experimentally known, while the most stable isotope of francium has a half-life of about 20 minutes. Francium's reactivity is therefore partially a matter of conjecture... the energy given off by its radioactive decay would literally vaporize any reasonably sized piece. That said, as an alkali metal francium would be much more reactive than uranium or plutonium, both of which are transition metals.
