Tīmeklis2024. gada 27. marts · Explanation: Plutonium- 239 has a mass of 239 amu. We know that the atomic number of plutonium on the periodic table is 94, as we can see it. And so, it'll have 239 − 94 = 145 neutrons. Since it is a neutral element, it'll have the same amount of electrons as protons, that is 94. Answer link. TīmeklisCollectively, protons 1–8 are assigned in Fig. 2. Notably, the chemical shifts of the protons in the O-connected benzene ring were shifted upfield to approximately 6.5 ppm for proton 2 and 6.1 ppm for proton 1 due to the electron-donating resonance effect of oxygen and the shielding effect induced by spatial overlap with adjacent aromatic rings.
