\nThe number 235 in Uranium-235 is the mass number (A), which is the total number of protons and neutrons in the nucleus. Uranium (U) has an atomic number (Z) of 92, meaning it has 92 protons. The number of neutrons (N) is calculated by subtracting the atomic number from the mass number: N = A – Z.
\n<\/section>\n
\n– Mass number (A) = Number of protons + Number of neutrons.
\n– Atomic number (Z) = Number of protons.
\n– For Uranium-235, A = 235 and Z = 92.
\n<\/section>\n
\n– Number of neutrons = 235 – 92 = 143.
\n– Uranium has several isotopes, including Uranium-238 (most common, 146 neutrons) and Uranium-235 (used in nuclear reactors and weapons, 143 neutrons).
