What is the only way to change one element into a different element?
through radioactive decay
A generalization of a behavior that always works in the same way under the same condition is a?
law
What is radioactive decay and how is it used to determine the absolute age of a rock?
every radioactive isotope has a measurable half-life, which is the time it takes for half the original isotope to decay to something else. So if we know how much was there originally, it's easy to calculate how long it's been decaying. In many cases we also use the product of the decay, which gives us a very good way to find out how much was originally there.
Do convection currents always affect the same way?
no
A rule or principle stating something that always works in the same way under the same conditions is a?
law
What formulas will give you the total value of a series of numbers displayed in column C from C1 to C14?
The simplest and best way is: =SUM(C1:C14)
Why can carbon-14 be used to date a 40000 year old tree but U-Pb cannot?
C14 is continuously made in the atmosphere by the effects of solar radiation on Nitrogen14. There is an equilibrium up there between how quickly C14 is made and how quickly it decays to C12 because the gases circulate. Obviously this circulation stops when a C14 molecule gets incorporated into a plant or something that ate the plant. Over time the C14 in a tree disappears while C14 in the iar keeps gettin renewed. Our dating technique relies on the difference between how much C14 is left in the tree compared to what can be found in the air. I dont think the same can be said of U. It and other heavy elements are not airborne and were in any case made in a dying sun. Therefore the ratio of Pu, U, Pb and other heavy elements is the same whether in a tree or in the soil that the tree grew up in. So while any U that found its way into the tree will have decayed, the U in the soil will have decayed too. Therefore our C14 (which relies on measuring differences) cannot be used. Full disclosure: I have MSc Molecular Biology but I am NOT an expert in carbon dating. Double check before you rely on this information as gospel.
Is radioactive decay the same as organic decay?
No, radioactive decay is not the same as organic decay. The basic difference between radioactive decay and organic decay is that in organic decay, chemical compounds break down and the biochemical structure of the subject changes. This is a natural process that any biological structures will undergo, or it could be induced. In either case, it represents a chemical change. In radioactive decay, the actual atomic nuclei of atoms will break down in some way, depending on the substance being considered. It is the unstable atomic nucleus of given isotopes of elements that undergoes the change, and this is a nuclear or atomic change.
The way you express the time it takes for atoms in a radioactive substance to distintegrate is called?
The time used for dealing with nuclear decay is called a half life. Decay of a radioactive atom is something that happens by change, and the atoms of one isotope may be more or less prone to decay than the atoms of another. The way we normally express the rate of decay is to speak of the amount of time it takes for half of the atoms in a sample to decay, which is the same as the time during which any one atom of the sample has a 50% chance of decaying.
What products are released during decay?
There are 4 different types of decay, the first is alpha decay this releases a helium nucleus ( 2 protons and 2 neutrons) the second is a beta particle also known as an electron. The third is beta minus decay which is a positron, it is the same as an electron in every way except it has a positive charge where as an electron has a negative charge. The last is gamma decay, which releases a gamma ray, this is a type of electromagnetic wave.
Why does insecticide effectivenes decay?
Designed that way for safety-the ones that don't decay fast enough have been banned
What is carbon-14 decay product?
Nitrogen-14, by way of beta decay.
Is there any way to prevent decay when a person is buried?
NO
What does decay mean in the dentist way?
It means to rot.
What is another way to age a fossil?
By radioactive decay process.
What is one way in which decay by micro organisms is a nuisance?
by muting
When an isotope is what it does not undergo radioactive decay?
friends are like seashells you collect on the way
