Step 1: Identify the mass number and atomic number from the given isotope notation. The notation for an isotope is ^A_ZX, where A is the mass number (protons + neutrons) and Z is the atomic number (protons). For the uranium nucleus ^238_92U: Mass number (A) = 238 Atomic number (Z) = 92 Step 2: Calculate the number of neutrons. The number of neutrons is found by subtracting the atomic number from the mass number. Number of neutrons = A - Z Number of neutrons = 238 - 92 Number of neutrons = 146 Step 3: Compare the calculated value with the given options. The calculated number of neutrons is 146, which corresponds to option B. The number of neutrons in the nucleus of ^238_92U is B) 146. Send me the next one 📸
