Step 2: Calculate the total mass of the individual nucleons (protons and neutrons).- Mass of 3 protons:Mass of protons=3×1.007277amu=3.021831amu - Mass of 4 neutrons:Mass of neutrons=4×1.008665amu=4.03466amu - Mass of 3 electrons (not needed for binding energy calculation, but included ...
? Assuming the atom is uncharged, how many electrons are present? Protons and Neutrons:Protons and neutrons constitute two sorts of subatomic particles. Protons are drawn towards a negative charge, as they constitute a positive charge. N...
With the transition radii for protons and neutrons chosen to be 3.9 fm and 4.1 fm respectively, good fits to the experimental cross sections are obtained. In contrast to the distorted wave Born approximation ( dwba ) calculations using optical model codes, we find the present work is able to...
Polarization of neutrons from the 7Li(p, n) 7Be reaction for 3 to 4 MeV protonsNUCLEAR REACTION 7Li (p, n), E=3-4 MeVmeasured polarization ( E) Natural targetSix values for the polarization of the neutrons emitted at 50掳 in the reaction 7Li(p, n) 7Be were obtained for proton ...
Balancing a nuclear equation is essential due to the conservation of charge, and is done by ensuring that the sum of the protons and neutrons of nuclei and particles in both sides of the equation are equivalent.Answer and Explanation:
1.The neutrons and protons form the core of the atom. 1.中和质构成了核。 2.Electrons are negatively charged with electricity,protons are positively charged. 2.电是带负电的,质是带正电的。 3.An electron has a negative charge,a proton has a positive charge. 3.电带负电,质带正电。 4.The...
