Respuesta :
the half life period of the rock sample remains unchanged.. it will always be 4.5*10^9 yrs doesn't matter how many times you cut it
The rock sample's half-life span remains constant. It will always be 4.5×10⁹ years no matter how many times it is cutting process.
What is uranium?
Uranium, with the atomic number 92 and the symbol U in the periodic table, is a weakly radioactive element. One of the heavy metals that may be used as a concentrated energy source is uranium.
The element is found in various rocks in concentrations of 2 to 4 ppm (parts per million).
The rock sample's half-life span remains constant. It will always be 4.5×10⁹ years no matter how many times it is cutting process.
Hence the half-life of the uranium remains unchanged.
