Nickel-62 (28 protons, 34 neutrons) has the highest mean binding energy of all nuclides, while iron-58 (26 protons, 32 neutrons) and iron-56 (26 protons, 30 neutrons) are a close second and third. [13] These nuclides lie at the very bottom of the valley of stability.
Iron-55 (55 Fe) is a radioactive isotope of iron with a nucleus containing 26 protons and 29 neutrons. It decays by electron capture to manganese-55 and this process has a half-life of 2.737 years. The emitted X-rays can be used as an X-ray source for various scientific analysis methods, such as X-ray diffraction.
One way of envisioning this effect is to imagine the 1s electron sitting on one side of the 26 protons in the nucleus, with another electron sitting on the other side; each electron will feel less than the attractive force of 26 protons because the other electron contributes a repelling force.

10 unhealthiest Thanksgiving side dishes. 1. Candied sweet potatoes. 2. Grandmother's buttermilk cornbread. 3. Awesome and easy creamy corn casserole
I reviewed five kinds of canned chili from the supermarket to find the best-tasting option. The meat-free version of Amy's was quite tasty, but the Campbell's Chunky chili mac was my favorite.
We put all the best artificial Christmas trees to the test, including Balsam Hill, King of Christmas, and Puleo International.
Subsequently, the 60 Fe lines (1.173 MeV and 1.333 Mev) were also detected showing the relative rates of decays from 60 Fe to 26 Al to be 60 Fe/ 26 Al ~ 0.11. [ 23 ] In pursuit of the carriers of 22 Ne in the sludge produced by chemical destruction of some meteorites, carrier grains in micron size, acid-resistant ultra-refractory materials (e.g ...
