Guida verificata passo dopo passo1
Identify the atomic number (Z) of the element, which is the number of protons. For tin (Sn), the atomic number is 50.
Identify the mass number (A) of the isotope, which is given as 118 in the notation 118^50Sn.
Recall that the number of neutrons (N) in an atom is calculated using the formula: N = A - Z.
Substitute the known values into the formula: N = 118 - 50.
Perform the subtraction to find the number of neutrons in the nucleus of the atom.
