Balance these nuclear equations 104/47 Ag -> 0/-1e +

1 answer

To balance the nuclear equation \( ^{104}{47} \text{Ag} \rightarrow ^{0}{-1} \text{e} + X \), you need to find the particle \( X \).

In this decay process, silver-104 (Ag) undergoes beta decay, where an electron (beta particle) is emitted. The decayed nucleus will typically be a different element or isotope.

  1. Start by noting the mass numbers and atomic numbers:

    • The mass number of Ag (104) is on the left.
    • The atomic number of Ag (47) is also on the left.
  2. The emitted beta particle \( ^{0}_{-1} \text{e} \) has:

    • A mass number of 0.
    • An atomic number of -1.
  3. To find \( X \), we can set up the following equations:

    • Mass number: \( 104 = 0 + \text{mass number of } X \)
    • Atomic number: \( 47 = -1 + \text{atomic number of } X \)

From the mass number equation: \[ \text{mass number of } X = 104 - 0 = 104 \]

From the atomic number equation: \[ \text{atomic number of } X = 47 + 1 = 48 \]

  1. The resulting nucleus with mass number 104 and atomic number 48 is \( ^{104}_{48} \text{Cd} \) (cadmium).

Thus, the balanced nuclear equation is: \[ ^{104}{47} \text{Ag} \rightarrow ^{0}{-1} \text{e} + ^{104}_{48} \text{Cd} \]
