Write a nuclear equation for the alpha decay of Pu.

Question

Quizplus · Accepted Answer

In alpha decay, an alpha particle (which consists of 2 protons and 2 neutrons) is emitted from the nucleus. This means the atomic number of the daughter nucleus will be 2 less than the parent nucleus, and the mass number will be 4 less. Given that the parent nucleus is 11ea6c49_d569_45cf_9875_25f6e6037253_TB6106_11Pu, which has atomic number 94 and mass number 249, the daughter nucleus will have atomic number 92 and mass number 245. Therefore, the correct nuclear equation for the alpha decay of 11ea6c49_d569_45cf_9875_25f6e6037253_TB6106_11Pu is:

11ea6c49_d569_45cf_9875_25f6e6037253_TB6106_11Pu → 11ec73a7_6718_2131_b38b_373c90f75d3e_TB6106_11 + 4He

The only option that matches this is B.
