700 million years
It takes approximately 700 million years for uranium 235 to decay to half of its original form.
The half-life of uranium-235 is 703 800 000 years.
If you think to uranium 235 the half life is 703 800 000 years.
703, 800,000
Uranium 234, 235 an 238 are all natural isotopes of uranium.Uranium 235- neutrons: 143- atomic mass: 235,043 929 918 ± 0,000 001 957- half life: 7,038.108 years- concentration in natural uranium: 0,7204 %- 235U is a fissile isotope
The half-life is 700 million years !
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
If you think to uranium 235 the half life is 703 800 000 years.
700 million years
Uranium is a radioactive element and conteneously disintegrate into smaller element, that time in which 1g of uranium becomes half g is known as half life period of uranium.

700 million (more exactly 703,8.106) years
Uranium 234, 235 an 238 are all natural isotopes of uranium.Uranium 235- neutrons: 143- atomic mass: 235,043 929 918 ± 0,000 001 957- half life: 7,038.108 years- concentration in natural uranium: 0,7204 %- 235U is a fissile isotope
One Half-Life :-)
The half-life is 700 million years !
Uranium-235 is an isotope of uranium making up about 0.72% of natural uranium.
Approx. 0,7 % uranium 235 in natural uranium.
There is no uranium isotope with 234 neutrons. The questioner almost certainly meant the uranium isotope with 234 nucleons, which is a naturally occurring isotope U234 otherwise element 92, with 142 neutrons.In which case its half life would be 252,000 years.
