Answer: C
Helium decays to form lithium. Which equation correctly describes this decay?

Helium is the smallest and the lightest noble gas and one of the most unreactive elements so it was commonly considered that helium compounds cannot exist at all or at least under normal conditions. Helium s first ionization energy of 24.57 eV is the highest of any element. Helium has a complete shell of electrons and in this form the atom does not readily accept any extra electrons nor …

The singlet excitations immediately decay (< 10 ps) to the S * state without the emission of radiation (internal degradation). The S * state then decays to the ground state S 0 (typically to one of the vibrational levels above S 0) by emitting a scintillation photon. This is … Sun Oct 30 2005 13:30:00 GMT-0500 (Eastern Standard Time) · Nuclear binding energy is the minimum energy that would be required to disassemble the nucleus of an atom into its component parts. These component parts are neutrons and protons which are collectively called nucleons.The binding energy is always a positive number as we need to spend energy in moving these nucleons attracted to each other by the strong nuclear force away from each other. In alpha decay which typically occurs in the heaviest nuclei the radioactive element decays by emitting a helium nucleus (2 protons and 2 neutrons) giving another element plus helium -4. In many cases this process continues through several steps of this kind including other types of decays (usually beta decay ) until a stable element is formed. This decay is only possible because the mass of the proton is less than that of the neutron. By the mass-energy equivalence when a neutron decays to a proton this way it attains a lower energy state. Beta decay of the neutron described above can be denoted by the radioactive decay : n 0 → p + + e − + ν e. where p + e − and ν Trace amounts of d...
