What determines which radioactive element will give more accurate measurement of a rock's age?
By looking at the half-life of a radionuclide (as well as its chemistry), we can select which one will be best for determining the age of rock. The longer the half-life, the "farther back" in time we can measure to discover some things about when it originated.
What factor is least important in determining the plant life in a biome?
Abiotic factor.
The half-life of an element is used in determining what characteristic of a particular rock?
The absolute age of a rock is determined by the amount of decay of certain elements as interpreted from their known half-life. The absolute age is stated in a number of years with a margin of error, as opposed to the relative age, which is more of a range of years in which the rock could have formed, based on index fossil evidence and the law of superposition.
What is the half-life of plutonium-239?
Plutonium has 20 isotopes; each isotope has another half-life. Please read: http://en.wikipedia.org/wiki/Isotopes_of_plutonium.
In what 2 ways can elements occur in nature?
An element can be created in a particle accelerator or fusion reactor. It can also be "made" by waiting out the half-life of an element further down on the periodic table.
The half-life of an element is important in determining the of a rock?
relative age
The half life of an element is important for determining the blank of a rock?
answer is b
The half- life of an element is important for determining the of a rock a decomposition rate b relative age c absolute age d mineral makeup?
Absolute Age
The half-life of an element is important for determining what characteristic of a rock A decomposition rate B absolute age C relative age D mineral makeup?
The half-life can be used to determine the absolute age because the original amount of the elements can be calculated from the current value.
Would this method for determining half-life work for an isotope that has a half-life of 4.2 years?

The time it takes for half of the radioactive element to decay is the element's what?
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
How long will it take half of a radioactive sample to decay?
The length of time depends on the element and isotope, but the point at which half of the sample has decayed is known as the half-life.
How can half lives be shortened?
Half life of an element can't be changed.. It is a characteristic of a radioactive element which is independent of chemical and physical conditions.. Half life is that time in which half of radioactive sample( i.e., a radioactive element) decomposes. So no matter what amount you take half life of an element remains same.
What is the characteristics of a parent element?
The most important is the half life; also the type of decay, energy of released particles.
The half-life of an element is important for?
The half-life of an isotope is how long it takes for half of the atoms in a mass to undergo radioactive decay. Say you have 40g of an elements isotope with a half-life of one year. After 1 year, there would be 20g of that isotope left, and 20g of a different isotope/element. After 2 years, there would be 10g, and so on...
Is the half-life of a chemical element one-half of the amount of a radioactive element to decay?
The half-life is the time that it takes for 1/2 of a material to decay.
As a sample of a radioactive element decays its half-life?
No, the half life remains exactly the same throughout
