Write two paragraphs explaining the phenomenon of alpha decay and beta decay.

α particle and β particle are released due to disintegration or decay of radioactive element.

Explanation:

Alpha decay

When a alpha particle is released from a redioactive element at time the daughter element that is formed has 2 unit less atomic number and 4 unit less atomic mass than that of parental element.

Beta decay

When a beta particle is being released at that the daughter element that is produced has one unit more atomic number and same atomic mass with respect to the atomic number and atomic mass of the parental element.

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell

the answer is c i believe
