What is the ratio of parent to daughter isotopes after eight half lives?
Wiki User
∙ 14y ago
100(.50)^.5 = 70.71%.
.50 represents the 50% remainder per half-life, taken to the power of .5 or the number of half-lives that pass, all multiplied by 100 to make the answer a percentage.

How many half-lives would be necessary for a sample of parent isotopes to decay to the point that only one-half of the sample is composed of parent isotopes?
One half life.
Is osmium radioactive?
Osmium is very weakly radioactive. There are seven naturally occurring isotopes of osmium, four of which are stable. The three radioactive isotopes all have very long half lives, but they account for 42.39% of it.
Is astatine odorless?
All the isotopes of astatine are radioactive and has very short half lives; consequently is a dangerous element.
What is neon's radioactivity including half-lives?
Neon is usually not radioactive in its natural state but does have several radioactive synthetic isotopes. It has a half-life of 38 seconds.
Is neodymium radioactive?
Neodymium is radioactive, though for most practical purposes it can be regarded as stable. 30.4% of neodymium is of two radioactive isotopes, but their half lives are very long, the shorter being 2,290,000,000,000,000 years. Like all other elements, neodymium has synthetic radioactive isotopes.
When does Parent and daughter isotopes occur?
The daughter isotope is the result of the radioactive disintegration of the parent isotope. For example radium is a product of the uranium disintegration.The two isotopes have different chemical (different atomic numbers, etc.), physical and nuclear properties.

One half life.

One half life.
How do you get custody of daughter who lives with one parent who is unstable?
Make sure the other parent is PROVEN unstable. Keep record of occurances.
How many half-lives have occurred in a rock containing one-fourth parent material and three-fourths daughter material?
2 half-lives have.
Does a noncustodial parent have to pay for teenage daughters car insurance?
Whoever your daughter lives with is the responsible party to cover her on their insurance policy!
Are regular isotopes originaly stable?
Some natural isotopes are stable or have half-lives greater than the age of the Universe. But other natural isotopes are radioactive and have finite half-lives. It all depends on the particular isotope.
What are the respective decay products of uranium potassium and rubidium?
There are 26 different isotopes of uranium, each with its own method of decaying. If we stick to the commonest isotopes, however, we are dealing with three naturally occurring isotopes, 234U, 235U, and 238U, one more that exists in nature only in trace amounts, 236U, and two that are synthetic but have relatively long half lives, 232U and 233U. All of these can decay by alpha emission, and all can decay by spontaneous fission. In addition 238U can decay by double beta emission. In an the case of alpha emission, the daughter atom is Thorium, with an isotope number four lower than that of the parent atom. The other main product of decay is an alpha particle, which is essentially a helium ion moving very fast. In the case of double beta emission, two neutrinos are emitted, two electrons are captured, converting two neutrons to protons, and 238Pu is the daughter isotope. This decay is very rare. The case of fission is rather unpredictable. There are two daughter atoms, and neutrons are emitted. The sum of the isotope numbers of the daughter atoms and the number of neutrons equals the isotope number of the parent. Some of the mass of the parent is also converted to heat. The daughter atoms are each very roughly half the mass of the parent. Since the parent is neutron rich, it is inevitable that the daughters will also be neutron rich, and this means the daughter atoms will be radiologically very unstable. More than half the products of fission of 235U have half lives of less than one year, and only 19.5% have half lives of over 100 years (though all of these have half lives of over 200,000 years).
Can a parent force a sixteen year old daughter to attend a tough love boarding school in California against her wishes?
Yes. Until she is 18, she lives were they tell her to.
Can the custodial parent who lives in 1 state file for child support in the state the non-custodial parent lives in?
of course
How fast did ununseptium decay?
The half lives of ununseptium isotopes are of the order of milliseconds.
If a child lives with one parent can the other parent who does not live in the same home claim that same child?
Not on taxes no. The parent the child lives with has the main right to claim the child. But if that parent can't or doesn't want to then the other parent can
