What happens in the process of radioactive decay? - Socratic
2017年11月29日 · When an unstable isotope undergoes radioactive decay radiation is emitted in the form of either alpha, beta, or gamma particles. 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 …
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 ...
How would you compare nuclear fusion, fission, and radioactive …
2016年2月15日 · 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 of an atom splits into smaller parts (lighter nuclei). The fission process often produces free neutrons and gamma photons, and releases a very large amount …
What happens to an atom that experiences radioactive decay?
2016年4月16日 · Radioactive decay is when the nucleus of an atom isn't stable - it could have too many protons that push each other apart, or too many neutrons, and it's just like a big lump of rock and can fall apart. There are three kinds of radioactive decay, all named after Greek letters: alpha (#alpha#), beta (#beta#) and gamma (#gamma#).
Nuclear Half-Life Calculations - Chemistry - Socratic
#A_0# - the initial quantity of the substance that will undergo decay; #t_("1/2")# - the half-life of the decaying quantity. So, if a problem asks you to calculate an element's half-life, it must provide information about the initial mass, the quantity left after radioactive decay, and the time it took that sample to reach its post-decay value.
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 · ""_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 beta decay, one of its neutrons is converted into a proton, with an electron and an antineutrino being emitted in the process.
Can transmutation occur through radioactive decay? - Socratic
2015年8月24日 · Yes. Transmutation can occur through alpha decay and beta decay. In alpha decay, a radioisotope with an unstable nucleus emits an alpha particle (two protons and two neutrons) and energy. For example, the uranium-238 radioisotope, which has an atomic number of 92, undergoes alpha decay to form thorium-234, which has an atomic number of 90. There …
Beta Decay - Chemistry - Socratic
Beta decay is the loss of an electron from the nucleus of an atom. In Beta decay, a high-energy electron (called a beta particle) is emitted from a neutron in the nucleus of a radioactive atom. That neutron may be thought of as a combination of a beta particle (negative charge) with a proton (positive charge). The loss of the negatively charged beta particle leaves behind a …
