It is stable and therefore does not neccessarily have a half life :D
Hope this helped :D xx
Carbon is an element, but not carbon dioxide. Carbon dioxide is a compound of carbon and oxygen.
The half-life of uranium-239 is 23.45 minutes.
About 1.1% of naturally occurring carbon is carbon-13.
B is the symbol for which element?Boron
Carbon is a pure element, while carbon dioxide is a compound consisting of one carbon atom and two oxygen atoms. Carbon is a solid at room temperature, while carbon dioxide is a gas. Additionally, carbon is essential for life and is found in all living organisms, while carbon dioxide is a greenhouse gas and a byproduct of combustion and respiration.
On an object with unknown age but more than halflife of C

Illadelph Halflife was created on 1996-09-24.
The half-life of Carbon-11 is approximately 20 minutes. This means that it takes about 20 minutes for half of a sample of Carbon-11 to decay into a stable isotope. Carbon-11 is commonly used in positron emission tomography (PET) imaging due to its short half-life.
Yes.
Carbon dating measures the amount of carbon halflives that an object's carbon-14 has seen. A halflife is the amount of time it takes for half of the C-14 present to decay into a different element (N-14). A carbon halflife is 5730 years so you wouldn't be able to tell with such a small amount of time.
The logo has a border, however the lambda is in the center.
Yes, but it has a halflife of only 0.86 seconds.
Go out and buy it. You can't download it.
The half life of plutonium-235 is 25,3(5) minutes.
The primary source of radioactivity in the human body is Carbon-14. However the level of Carbon-14 remains constant in the body as the human body is in equilibrium with the atmosphere as long as the body is alive. Therefor there is no halflife until the body dies; then it matches the halflife of Carbon-14.
You need to know the activity at the start of the interval in question. You measure the activity at the end of the interval in question, compare the two, and back calculate the age. Commonly, in Carbon-14 dating, we use the ratio of Carbon-14 to Carbon-12/Carbon-13, and calibrate by using other methods of dating. This works because the ratio is (relatively) constant when the carbonaceous material is alive, and starts to decay with a 5700 year halflife at death.
