What are isotopes of boron?
Boron-11 (80%) and boron-10 (20%).
Is boron radioactive?
There are no radioactive isotopes of boron that are ordinarily found in nature. All elements have synthetic radioactive isotopes, however.
What is meant by half life of radioactive isotopes?
This is the time in which half the the atoms was disintegrated.
Which of these illustrations shows isotopes of the element boron?
1 and 3
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.
How many isotopes are in boron?
There is 13 isotopes in the element boron. xD
What is the half life of boron?
The half-life of beryllium varies according which isotope of this element we consider. There are a number of isotopes, and half-lives range from a small fraction of a second to many thousands of years. Use the link below to see a list of the isotopes of beryllium and their half-lives.
What are isotopes of boron?
Boron-11 (80%) and boron-10 (20%).
How many isotopes does boron have?
Two stable ones, 10 & 11. Several unstable.
Who describes an isotopes half life?
Half-life is described in time units.
Is boron radioactive?
There are no radioactive isotopes of boron that are ordinarily found in nature. All elements have synthetic radioactive isotopes, however.
Why are radioactive isotopes and half life important to science?
half life tell time
What is the half life of arsenic?
Arsenic (in the form of arsenic-75) is a stable element. Only its isotopes have a half-life. As there are many isotopes of every element, and each has a different half life, it is difficult to specify a precise answer. The related link below contains a list of known isotopes and their half lives.
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.
What is meant by half life of radioactive isotopes?
This is the time in which half the the atoms was disintegrated.
What is the half-life of every radioactive element?
The same element can have different half-lives, for different isotopes. You can find a list at the Wikipedia article "List of radioactive isotopes by half-life". This list is NOT complete; a complete list would have about 3000 nuclides (that is, isotopes).
Do isotopes determine the size or age of a rock?
age... parent and daughter isotopes in relation to half life
