How much energy is required to make a Iron atom from hydrogen atoms |
|
Answer» know the mass of a nuclide, the ENERGY released in its formation from Z protons (A-Z), neutron and Z electrons is GIVEN by the difference Z(me +mp ) + (A-Z) mn - mnuclide multipied by c2. for EXAMPLE m(U -238) = 238.05078826 u = 1,66054 × 10−24 x 238.05078826 = 3.9529 10-22 g mp=1.6726219 × 10-24 g me =9.10938 ×10−28g mn = 1.674927×10−24 g Z(me +mp ) + (A-Z) mn = 3.9850436 x 10-22g Difference = 3.2143631 x 10-24 g = 3.2143631 x 10-27 KG Energy released= difference x c 2 = 2.8889255 10-10 J |
