Which states supplies about half of your country uranium?

Kazakhstan supplies about half of the world's uranium production, making it one of the leading uranium-producing countries.


Why is lead found in all deposits of uranium ores?

Lead is often found in uranium deposits because they have similar chemical properties and tend to form together during the same geological processes. As uranium ores break down over time, lead is a common byproduct of the radioactive decay of uranium. This is why lead is commonly found in association with uranium deposits.


What element has 125 atomic number?

The element with atomic number 125 is unknown, as it has not been discovered or named yet. Elements beyond uranium (atomic number 92) are typically synthesized in laboratories and have very short half-lives.


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.


How old is a rock for which you determine that 55 percent of the original uranium-238 remains while the other 45 percent has decayed into lead?

The rock would be approximately 1.51 billion years old. This estimation is based on the known half-life of uranium-238, which is about 4.5 billion years. By determining that 55 percent of the original uranium-238 remains, you can infer the age of the rock by calculating how many half-lives have passed.
