Cyanocobalamin is the most common and widely produced form of the chemical compounds that have vitamin B12 activity.
For example, the hadron constituents of atomic nuclei, neutrons and protons, have charges of 0 e and +1 e respectively; the neutron is composed of two down quarks and one up quark, and the proton of two up quarks and one down quark.
The element, uranium, has an atomic number of 92. That means that, assuming it's electrically neutral, it has 92 protons and 92 electrons. Since we know that this particular i â¦ sotope of uranium has a combined total of 238 protons and neutrons, the total number of neutrons in 238U is 238 - 92 = 146. Uranium 238 has: 92 protons, 92 electrons and 146 neutrons.
