How old is a bone in which the carbon-14 has undergone 3 half-lives?
11,000 yeard
What does an atom of carbon 14 contain?
It contains 6 protons, 8 neutrons, and 6 electrons
How old is a piece of wood that has 0.7813 percent of the carbon-14 of a living organism?
40110 years
How many protons neutrons and electrons in carbon-14?
Carbon 14 has 6 protons, 8 neutrons, and (in the neutral atom) 6 electrons.
What is the age of a prehistoric mummified human skin that contains 12.5 percent of the original amount of carbon-14?
The half life of C-14 is about 5730 years and 12.5% is 100% x (.5)^3 so 3 half lives of the C-14 have occured. Now all you do is multiply 5730 years by 3 and get 17190 years. That's pretty old!
How old is a dinosaur bone containing 50 percent carbon 14 and 50 percent nitrogen 14?
Dinosaur bones won't have any C14; that's all used up in about 50,000 years. The "freshest" dino bone you can find will be at least 65,000,000 years old. Actually, the dino bone will be so mineralized that there really won't be any "bone" left.
How many neutrons does the element carbon have?
Carbon 12 the most common contains 6 Carbon 13 contains 7 Carbon 14 contains 8
How old is an artifact that contains 12.5 percent of its original carbon-14?
The artifact is approximately 17,500 years old. This calculation is based on the half-life of carbon-14, which is about 5,730 years. By determining the percentage of remaining carbon-14 in the artifact, scientists can estimate its age.
How much percent carbon in 1114 steel?
.14%
In what terms do carbon-14 differs from carbon-12?
Carbon fourteen contains two more neutrons as compared to carbon twelve.
Which element is used for archaeological discoveries?
Carbon-14 dating is commonly used in archaeology to determine the age of organic materials, such as bone and charcoal. This method measures the radioactive decay of carbon-14 isotopes in the sample to estimate its age.
How old is a bone in which the carbon-14 has undergone 3 half-lives?
11,000 yeard
Carbon 14 has a half life of 5715 years it is used to determine the age of ancient objects if a sample today contains 0.060mg of carbon 14 how much carbon 14 must have been present in 430 years ago?
.06798mg
An atom of carbon-14 contains how many protons?
All carbon atoms have 6 protons, which is why carbon's atomic number is 6. All neutral carbon atoms have 6 electrons. The number of neutrons in a carbon-14 atom is its mass number minus its atomic number, 14 - 6 = 8 neutrons.
What is radiocarbon in archeology?
Carbon atoms are contained in most cells of all living things on Earth. Most carbon atoms (98.89 percent) are called carbon-12 because they have 6 neutrons and 6 protons in their nuclei. Most of the remaining atoms (1.11 percent) have 7 neutrons along with their 6 protons and are called carbon-13 atoms, but a very small quantity (called a trace amount) of carbon atoms have 8 neutrons and 6 protons. These and are called carbon-14 atoms. Carbon-14 atoms are radioactive and are referred to as radiocarbon. They are unstable, and decay slowly by releasing electrons before evolving into nitrogen-14 atoms. A living organisms constantly absorbs carbon in its body systems by respiration and processing nutrients, and the amount of carbon-14 it contains remains fairly constant for as long as it lives. The carbon-14 decays without being replaced after the organism dies and half of the carbon-14 nuclei will disintegrate in about 5,730 years. The amount of carbon-14 that has disintegrated in a fossilized organism can be calculated and used for determining its age.
