alpha radiation

阿尔法衰变

Alpha decay

α衰变或α衰变是一种放射性衰变,其中原子核发射α粒子,从而转变成质量数小于4的原子,而原子数小于2的原子。 例如,通过α粒子发射而形成钍-234的铀-238可以表示为:由于α粒子与氦-4原子的核相同,由两个质子和两个中子组成,因此具有质量 数字4和原子数2 - 这也可以写成:注意,在核方程的两边,质量数和原子序数都保守:质量数在左侧和右侧是238 ,原子序数在左侧和右侧为92。 α粒子也具有电荷+2,但是电荷通常不是写在核方程中,其描述核反应而不考虑电子。 这个惯例并不意味着核必然发生在中性原子中。 阿尔法衰变通常发生在最重的核素中。 Alpha decay, or α-decay, is a type of radioactive decay in which an atomic nucleus emits an alpha particle and thereby transforms into an atom with a mass number 4 less and atomic number 2 less. For example, uranium-238 decaying through α-particle emission to form thorium-234 can be expressed as: Because an alpha particle is the same as the nucleus of a helium-4 atom - consisting of two protons and two neutrons and thus having mass number 4 and atomic number 2 - this can also be written as: Notice how, on either side of the nuclear equation, both the mass number and the atomic number are conserved: the mass number is 238 on the left side and on the right side, and the atomic number is 92 on the left side and on the right side. The alpha particle also has a charge +2, but the charge is usually not written in nuclear equations, which describe nuclear reactions without considering the electrons. This convention is not meant to imply that the nuclei necessarily occur in neutral atoms. Alpha decay typically occurs in the heaviest nuclides.
