Respuesta :

1) Nuclear reaction.

[tex]_{90}^{232}Th\rightarrow_{88}^{228}Ra+_2^4He[/tex]

2) Types of radioactive decay.

2.1- Alpha decay: the nuclei emit an alpha particle. The mass number decreases by 4, and the atomic number increases by 2.

2.2- Beta-decay: the nuclei emit a fast-moving electron. The mass number does not change, and the atomic number increases by 1.

2.3- Gamma decay: the nuclei emit excess energy. The mass number and the atomic number do not change.

According to the information above the nuclear equation corresponds to an alpha decay.
