What else can I help you with?
Can lead be returned to uranium?
No, lead cannot be converted back into uranium. Once uranium has decayed into lead, it cannot be reversed.
Is uranium a gas?
No, uranium is a solid metal.
What is uranium hexafluoride made from?
Uranium hexafluoride is made from uranium dioxide or uranium tetrafluoride by adding fluorine gas. The process involves reacting uranium compound with an excess of fluorine gas under controlled conditions to produce uranium hexafluoride.
Is the density of hydrogen gas lower than that of uranium hexafluoride gas?
Yes, the density of hydrogen gas is lower than that of uranium hexafluoride gas. Hydrogen gas is one of the lightest elements, while uranium hexafluoride gas is much denser due to the heavy uranium atom.
How much time will elapse before only one - fourth of the decayed uranium 237 sample is left?
3,375 days
Which of these energy sources is formed from decayed and compressed plankton?
Natural Gas
What is the noble gas configuration for uranium?
The noble gas configuration for uranium is [Rn] 5f3 6d1 7s2. This means that the electron configuration for uranium can be shortened to make it like a noble gas (radon) by including the noble gas before uranium in square brackets.
Is uranium volatile or neon?
Uranium is a metal, non-volatile; neon is a gas.
What is the half-life of uranium 239?
Pu-239 has a half-life of 24,110 years.
Does uranium off gas an oder?
Radon, an odorless radioactive gas.
A meteorite is determined to be 4.5 billion years old. It now has 78 atoms of lead-206. Assuming no loss of daughter isotopes how many atoms of uranium-238 did the meteorite have to begin with The hal?
To determine the initial number of uranium-238 atoms, we can use the decay relationship between uranium-238 and lead-206. The half-life of uranium-238 is about 4.5 billion years, meaning that after one half-life, half of the uranium-238 would have decayed into lead-206. Since the meteorite now has 78 atoms of lead-206, it suggests that there were originally 78 atoms of lead-206 plus 78 atoms of uranium-238 that decayed to lead-206, totaling 156 atoms of uranium-238 initially.
If you start with 60 atoms of uranium - 238 how many remain after 4470000000 years?
After 4.47 billion years, roughly half of the original atoms of uranium-238 would have decayed to lead-206 through alpha decay. This means there would be about 30 atoms of uranium-238 remaining.
