What is the nuclear decay equation for protactinium-231?

Answer 1

The equation for the alpha decay of 222Rn is: 86222Rn --> 84218Po + 24He

Where He represents the alpha particle, which can also be viewed as a Helium nucleus.

Answer 2

225Ac---------α-----→221Fr (half-life = 10 days)

The equation for the alpha decay of 225Ac is:

89225Ac --> 87221Fr + 24He

representing the alpha particle as a helium nucleus.

Answer 3

The equation for the alpha decay of 213At:

85213At --> 83209Bi + 24He

where the alpha particle is represented as a helium nucleus.

Answer 4

The equation for the alpha decay of 231Pa is: 91231Pa --> 89227Ac + 24He

representing the alpha particle as a helium nucleus.

Answer 5

The equation for the beta decay of 239Np is:

93239Np --> 94239Pu + -10e

where -10e represents a negative beta particle or electron.

Answer 6

The equation for the alpha decay of 222Rn is: 86222Rn --> 84218Po + 24He

Where He represents the alpha particle, which can also be viewed as a Helium nucleus.
