   # How to write equations for radioactive decay

Following the somewhat serendipitous discovery of radioactivity by Becquerel, many prominent scientists began to investigate this new, intriguing phenomenon. During the beginning of the twentieth century, many radioactive substances were discovered, the properties of radiation were investigated and quantified, and a solid understanding of radiation and nuclear decay was developed. The spontaneous change of an unstable nuclide into another is radioactive decay. The unstable nuclide is called the parent nuclide ; the nuclide that results from the decay is known as the daughter nuclide.  ## Differential Equations    ## Nuclear equations and half-life – Mrs Wolsey Science

The radioactive decay law can be derived also for activity calculations or mass of radioactive material calculations:. The radioactive decay law states that the probability per unit time that a nucleus will decay is a constant, independent of time. This constant probability may vary greatly between different types of nuclei, leading to the many different observed decay rates. The radioactive decay of certain number of atoms mass is exponential in time.   ### Alpha Decay Nuclear Reaction Example Problem

Many nuclei are radioactive; that is, they decompose by emitting particles and in doing so, become a different nucleus. In our studies up to this point, atoms of one element were unable to change into different elements. That is because in all other types of changes discussed, only the electrons were changing. In these changes, the nucleus, which contains the protons that dictate which element an atom is, is changing.     Write balanced equations for nuclear decay using the names and symbols of common nuclei and particles. Beta decay — one neutron decays to a proton and an electron. This electron is emitted as a beta particle. 5 comment ## 03.05.2021 17:51:45 Roberto B.:

Thanks for this phenomenal course. ## 04.05.2021 8:46:15 Frederick W. K.:

Thanks a lot guys! ## 06.05.2021 0:22:53 Antonio L.:

I had chosen a tourism topic that was giving me a headache when searching for materials. ## 07.05.2021 13:28:40 Jimmy O.:

I must say that they are the right choice, they delivered quickly and most importantly error-free write up. ## 11.05.2021 19:57:35 Hector R.:

Make use on any trial run provides and weigh up each useful resource on its merits.
