Question

Hello! I need help answering questions 3 and 4 3.) Look at the equation below. What type of nuclear decay is this an example of? a.) alpha decay b.) beta decay c.) gamma decay 5.) during nuclear ____ two or more lighter atoms combine into a larger one

Answer 1

1) Nuclear reaction.

`_(90)^(232)Th\rightarrow_(88)^(228)Ra+_2^4He`

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.
