The half-life of carbon-14 is 5730 years. How long will it take for the number of carbon-14 nuclei in a sample to drop to a quarter of the original number?

5370 years. A half-life is how long a radioactive object takes for half of all its atoms to become new elements. 100 is half of 200 =)

∙ 14y ago5,370 years. That's what a half-life is. It is how long an atom or isotope takes for half of it to decay.

C14 decays to C12. The final product of the decay of 200g C14 is ~172g C12.

Why do electrons stay mostly between the two nuclei?
In a chemical bond, electrons reside between the two nuclei rather than inside the nucleus, because the nuclei have protons (positive charges) that repel the electrons.
What is characteristic of a covalent bond?
Electrons are shared between two different nuclei.
When the nuclei of hydrogen and lithium are fused together what element is produced?
When the nuclei of hydrogen and lithium are fused together, helium is produced.
How do you measure the distance between nuclei?
The distance between nuclei can be measured using techniques such as X-ray crystallography, NMR spectroscopy, or electron microscopy. These methods rely on the interaction of radiation or particles with the atomic structure of the molecules to determine the distance between nuclei. The data obtained from these experiments can then be used to calculate the distances between nuclei in a molecule.
The nuclei of all atoms have?
The all have protons.
All radioactive nuclides of an element have the same half life?
No, halflife is a bulk statistical property of a quantity of an isotope of an element.Individual nuclei do not have halflives, instead they have a probability of decaying at the current moment of time.
What is the percentage of radioactive nuclei left after 3 half lives have passed?
12.5%
Are the nuclei of final elements produced by nuclear decay more stable or less stable than the nuclei of original radioactive elements?
Of course they are more stable, therefore they formed naturally.
What fraction of a radioactive nuclei remain after p half lives?
The remainder is 2-p or 0.5p of the original amount.
Cell division resulting in two new nuclei having the same number of chromosomes as the original nucleus is called?
fission
How many time nuclus divided in meiosis?
3 times and the original so you get 4 nuclei (one for each cell)
Does a plant have a nuclei?
its cells have nuclei
Are pollen grains haploid or diploid if they have two nuclei the generative and the tube nuclei?
Pollen grains with generative and tube nuclei have two haploid nuclei.
What was the basic reason to call the resulting nuclei of any disintegrating nuclei as a Daughter nuclei either v can call it as a son son nuclei?
paaaaaaaaaaaaagal
What is the distance between nuclei in a hydrogen molecule br2?
