    2)In the proton-proton process, four hydrogen nuclei are used to produce one helium nucleus. This process releases energy because the mass of the helium nucleus is ______Less than_____ the mass of the hydrogen nuclei. 

    3)What do you need to do to start a fusion reaction? 

       c)both nuclear bombardment and intense heat and pressure 

    4)Nuclear power plants used for electricity generation are powered by ___Nuclear fission___ reactors. 

    5)What is the energy equivalent of the mass of an electron (9.1 x 10-31 kg)?

    Ans: It has a value of about 9.109×10−31 kilograms or about 5.486×10−4 daltons, equivalent to an energy of about 8.187×10−14 joules or about 0.5110 MeV.
