How would you compare nuclear fusion, fission, and radioactive …
2016年2月15日 · 3.Radioactive decay is the breakdown of an atomic nucleus resulting in the release of energy and matter from the nucleus. Answer link. nuclear fusion is a nuclear reaction in which two or more atomic nuclei come very close and then collide at a very high speed and join to form a new nucleus. 2.nuclear fission is a process in which the nucleus ...
Why does carbon 14 undergo radioactive decay? - Socratic
2015年5月29日 · Carbon-14 is radioactive because it has too many neutrons for the number of protons. > The principal factor that determines whether a nucleus is stable is the neutron to proton (n:p) ratio. The diagram below plots the number of neutrons versus the number of protons in the first 15 elements. The black squares represent stable isotopes. They are called the band of …
What is radioactive decay? + Example - Socratic
2015年10月17日 · During radioactive decay, particles and energy called radiation are are released by atoms of the radioactive element. Radioactive decay is the term used to describe the process by which an unstable atom loses energy to its surrounding environment. With radioactive decay, the nucleus of the atom changes from a parent nuclide to a daughter nuclide.
How does radioactive decay relate to radiometric dating?
2015年8月29日 · The ease of using the formula for radioactive decay with common elements found in nature make it a powerful tool. Radiometric dating is the technique of using isotopic ratios of common elements to determine the age (approximate) of materials associated with the element, such as trees, rock strata, fossils, human artifacts and the like. Because radioactive …
What happens in the process of radioactive decay? - Socratic
2017年11月29日 · Explanation: When an unstable isotope undergoes radioactive decay radiation is emitted in the form of either alpha, beta, or gamma particles. Alpha or beta emissions may result in a change in the number of protons within the nucleus. A change in the number of protons changes the radioactive isotope into a more stable isotope.
How is radioactive decay related to half life? - Socratic
2016年4月5日 · The faster the decay, the shorter the half life. Half life (mathematically T_(1/2)) is how long it takes for half of the atoms in a substance to radioactively decay. If you want to know the maths behind their relationship, N = N_0e^(-lambdat) applies to radioactive substances, where N is the number of radioactive atoms at time t N_0 is the number of radioactive atoms at the …
Nitrogen-17 is a beta emitter, what is the isotope produced in the ...
2015年12月15日 · Therefore, the isotope produced by the beta decay of nitrogen-17 will be oxygen-17. 17 7 N → 17 8 O +0 -1e + ¯νe. Answer link. ""_8^17"O" In order to figure out what isotope is produced when nitrogen-17 undergoes beta decay, you first need to make sure that you understand what beta decay actually is. As you know, when an isotope undergoes ...
How is nuclear stability related to radioactive decay?
2014年3月16日 · An unstable nucleus tries to become more stable by decaying into another nucleus. During radioactive decay, an unstable nucleus emits alpha particles, beta particles, positrons, or gamma rays. ALPHA PARTICLES: An alpha particle is a helium nucleus. The heavier elements usually decay by alpha emission. For example, ₉₂²³⁸U → ...

2017年5月31日 · If a radioactive Isotope has a half life of 30 days then how long will it take 1000 grams to... If the half life of an unstable element is 5000 years, what percentage of the parent material... How much material will be left if a radioactive isotope has a …
The half life of Carbon-14 is 5730 years, how many years ... - Socratic
2017年12月30日 · 17190 years. The half-life of carbon-14 is 5730 years. Therefore, after 1 half-life there is 50%=1/2 of the original amount left. 2 half-lives there is 25%=1/4 of the original amount left. 3 half-lives there is 12.5%=1/8 of the original amount left. 1-7/8=1/8 So, your answer would be the time it takes for carbon-14 to elapse 3 half-lives. 5730*3=17190
