Why is the mass of a nucleus always less than the sum of the masses of its constituents-neutrons and protons? View Solution If M is the mass of a nucleus and A its atomic mass, then the packing fraction is: View Solution Doubtnut is No.1 Study App and Learning App with Instant Video...
To solve the problem of finding the kinetic energy of the alpha particle when the nucleus21084Poundergoes alpha decay, we will follow these steps: Step 1: Write the Alpha Decay Reaction The alpha decay of21084Pocan be represented as:
This process changes the nuclear composition of the nucleus of an atom through an emission of particles. The type of radiaoctive decay typically depends on the particles that are converted and emitted after the reaction. Some of the common radioactive decays includ...
mass在这里应该是质量的意思，这句话的意思是说一个原子的所有质量几乎都在它的原子核上。the mass of an atom 指的是任意一个原子， a mass of 才表示大量其实看你怎么理解啦！an atom里自然有一个总量，那么the mass of就是它的大量了。换句话说，mass可以跟可数，也可以跟不可数，单数也有大...
How does the mass of a nucleon compare with the mass of an electron? Nucleon: Nucleon is a term used to refer to either a proton or a neutron. The term "nucleon" is not really necessary, but it is used to distinguish protons and neutrons that are bound to the nucleus of ...
