145 plus 68 is equal to 213.
237
It is 145
Uranium-237 has 142 neutrons. This can be determined by subtracting the atomic number (92) from the atomic mass (237) of uranium-237.
Uranium-237 has 92 protons (as all uranium isotopes do) and typically 145 neutrons. This would make the total number of electrons in uranium-237 equal to the number of protons, which is 92 electrons.
163 + 432 + 237 + 548 = 1,380
237 + 416 = 653
237 + 63 = 300
237 + 195 + 5 = 437
s = -145
42 + 35 + 33 + 27 + 39 + 32 + 17 + 12 = 237
