Radioactive isotopes have unstable nuclei that slowly break apart over time. As they decay, bits of the nucleus (protons and neutrons) are emitted which can cause damage to substances and organisms that are struck by these particles. The simplest type of radiation is the Alpha particle, which is emitted by all elements whose atomic number is 84 or greater. 1. If each alpha particle has the same composition as the nucleus of a Helium atom, how many protons and neutrons...

An isotope emits an electron and an anti-neutrino during radioactive decay. The 11. electron moves east with a momentum of 9.28 x 1028 kg m/s and the anti-neutrino moves north with a momentum of 7.47 x 1027 kg m/s as shown in the diagram below. electron recoiling nucleus a. Determine the momentum of the recoiling nucleus. Determine the angle to the nearest 1/100th degree. 3) Answer If scientists only knew where the electron and recoiling nucleus went, which conservation law...

True or False 6. Carbon-14 is a radioactive isotope of carbon. . 7. The 3 isotopes of hydrogen differ in the number of protons? 8. The kinetic energy does a 1000 Kg car have going 15 m/s is 15000 Joules. 9. A metal weighs 100 kg and has a volume of 4 m3 has a density400 kg/m. 10. Radiation is the process of transferring heat from one material to another by contact. 11 The normal hearing range is between 20...

The nucleus can become unstable when it contains more protons than neutrons because: 1. exchange forces compete with Coulombic forces 2. exchange forces cause neutrons to repel each other 3. exchange forces cause protons to repel each other 4. exchange forces have a shorter range than coulombic forces
Suppose a radioactive sample initially contains N0 unstable nuclei. These nuclei will decay into stable nuclei,...
Suppose a radioactive sample initially contains N0 unstable nuclei. These nuclei will decay into stable nuclei, and as they do, the number of unstable nuclei that remain, N(t), will decrease with time. Although there is no way for us to predict exactly when any one nucleus will decay, we can write down an expression for the total number of unstable nuclei that remain after a time t: N(t)=N0e−λt, where λ is known as the decay constant. Note that at t=0,...
