half life indicates in how much time half will be gone so in 8.07 half of the 5.0g will be gone leaving 2.5 then after another 8.07 half of the 2.5 will be gone and this will happen 5 times in 40.35 days (40.35/8.07) so it (1/2)^5 * 5g leaving 0.15625g

160 mg of any radioactive substance will decay to 5.0 mg in 5 half lives.
160/5 = 32. 32=2^5. Or, if you prefer, 1/32 = 1/2^5.
0.7mc is left after 40 days

That's called a daughter isotope, or a daughter product. (The original isotope that decayed is the parent isotope.)
An isotope of an element that is radioactive
a radioactive isotope of hydrogen with a mass approximately three times that of the common protium isotope
Yes because it can replace the phosphorus atom in the phosphate group.
It tells how long it takes for a radioactive isotope to become a daughter element.
no, halflife is a constant for each isotope's decay process.
many. one example is lead-214 with a halflife of 26.8 minutes.
The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.
halflife
Making any change in the half-life of an isotope of any element is generally something that lies outside our abilities. A very few radioactive materials have demonstrated a change in their half-lives when bathed in intense magnetic fields. Generally, however, the half-life on a given radionuclide is not something that can be changed. A number of experiments have been conducted wherein investigators have deliberately sought to influence radioactive half-life, but in all but the rarest cases, radionuclides are sublimely resistant to having their half-lives changed.
When an isotope is unstable, it is said to be radioactive.
No, halflife is a bulk statistical property of a quantity of an isotope of an element.Individual nuclei do not have halflives, instead they have a probability of decaying at the current moment of time.
The radioactive isotope is disintegrated in time and emit radiations.
The radioactive isotope is disintegrated in time and emit radiations.
Yes, but it has a halflife of only 0.86 seconds.
The length of time required for half of a sample of radioactive material to decay
when an isotope is it does not undergo radioactive decay
