What number is written after the isotope when writing the name?
The atomic mass number of that isotope. So C14 has a molecular mass of 14 grams/mole U238, 238 grams/mole
What isotope serves as the current standard for the atomic mass scale?
with C14 atom
Which metal or non metal have atomic number 6?
Carbon has the atomic number 6. Its mass number (to the nearest integer value) is 12, and it has two isotopes, C12 and C14, the latter of which is radioactive.
What is the daughter product of the nuclear decay equation of C14?
N14
Radioactive form of this element is used in dating ancient objects?
C14 (carbon) isotope (mass number 14 that is, in stead of 12) if it is of organic origin, eg. wood, coal, mummy's clothe

Why is more C-14 found in new bone than in ancient bones of the same mass?
Because C14 will gradually disintegrate.
What are the release dates for C14 - 2013?
C14 - 2013 was released on: USA: 30 October 2013 (limited)
What formulas will give you the total value of a series of numbers displayed in column C from C1 to C14?
The simplest and best way is: =SUM(C1:C14)
Why can carbon-14 be used to date a 40000 year old tree but U-Pb cannot?
C14 is continuously made in the atmosphere by the effects of solar radiation on Nitrogen14. There is an equilibrium up there between how quickly C14 is made and how quickly it decays to C12 because the gases circulate. Obviously this circulation stops when a C14 molecule gets incorporated into a plant or something that ate the plant. Over time the C14 in a tree disappears while C14 in the iar keeps gettin renewed. Our dating technique relies on the difference between how much C14 is left in the tree compared to what can be found in the air. I dont think the same can be said of U. It and other heavy elements are not airborne and were in any case made in a dying sun. Therefore the ratio of Pu, U, Pb and other heavy elements is the same whether in a tree or in the soil that the tree grew up in. So while any U that found its way into the tree will have decayed, the U in the soil will have decayed too. Therefore our C14 (which relies on measuring differences) cannot be used. Full disclosure: I have MSc Molecular Biology but I am NOT an expert in carbon dating. Double check before you rely on this information as gospel.

C14 bouble barrel shot gun?
Yes.
What is the chemical formula of lidocaine?
C14 h22 n2o
The half-life of C14 is 5730 years. What fraction of the original C14 would you expect to be present in a fossil that is 28650 years old?
There would be 1/32 left.
What half-life of C14 is 5730 years. What fraction of the original C14 would you expect to be present in a fossil that is 28650 years old?
1/32 of the original amount.
What is the difference between c 12 and c 14?
C12 and C14 are isotopes of the Element Carbon. C12 is the most abundant of all which is 99% of all the Carbon on earth while C14 is only 0.0000000001% (trace amount). C12 has a Atomic Number of 12. It has 6 Protons and 6 Neutrons. C14 has a Atomic Number of 14. It has 6 Protons and 8 Neutrons. C14 is radioactive in nature. It is used for carbon dating.
