Follow us:

Q1. Write the nuclear equation for the alpha decay of Ra-224.

Q2. Write the nuclear equation for the alpha decay of Po-216.

Begin with the symbol for Ra-224 on the left side of the equation and the symbol for an alpha particle on the right side.

Equalize the sum of the mass numbers and the sum of the atomic numbers on both sides of the equation by writing the appropriate mass number and atomic number for the unknown daughter nuclide.

Refer to the periodic table to deduce the identity of the unknown daughter nuclide from the atomic number and write its symbol. Since the atomic number is 86, the daughter nuclide in this example is radon (Rn).

Correct me if I'm wrong, but isn't the 82nd element Lead?

This are awesome examples however, isn't the 82nd element suppose to be lead not bismuth because bismuth is 83...but other than this, great video!
