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.
Is Element 115 in real life?
Yes, Element 115 is a real chemical element on the periodic table. It was discovered and named moscovium (Mc) in 2003. It is a highly unstable element with a very short half-life.
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.
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 element is may?
The element May (Meitnerium) is a synthetic element with the atomic number 109. It is a radioactive element and is produced in nuclear reactors by bombarding lighter elements with atomic particles. May is a highly unstable element with a very short half-life.
The half life of an element is important for determining the blank of a rock?

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 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.
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.
Would this method for determining half-life work for an isotope that has a half-life of 4.2 years?

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.
How does the half life of element Z compare to the half life of carbon-14?
The half-life of an element is the time it takes for half of a sample to decay. It is specific to each element. The half-life of carbon-14 is 5730 years, whereas the half-life of element Z would depend on the specific element and is not necessarily comparable to carbon-14.
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.
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...
How long will it take half of a radioactive sample to decay?
The time it takes for half of a radioactive sample to decay is known as the half-life. Each radioactive element has a unique half-life, which could range from fractions of a second to billions of years. The half-life remains constant regardless of the size of the initial sample.
Why is the half life of an element important?
The shorter the half-life the greater the danger of radiation causing us harm. If you have two equal masses of radioactive material with different half-lives, the one with the shorter half-life will release more radioactivity in a given time than the one with the longer half-life.
