Question

Write short notes on theory of $\alpha-$ decay.

Answer 1

Answer:

Explanation:

In alpha decay,a product known as doubly ionised helium atom is formed.The decay takes place, obeying the law of conservation of mass and energy.Thus,there is a decrease in mass number by four units and a decrease in atomic number by two units in the product.It is a spontaneous disintegration of an unstable nuclei into a more stable one.

Example:-Disintegration of radium to radon.

Answer 2

$\huge \purple \bigstar \underline \mathfrak \green{answer}$

in Alpha decay, a product known as doubly ionized Helium atom is formed. the Deccan take place, obeying the law of conversation of mass and energy. Thus, there is a decrease in mass number by four units and a decrease in Automic number by two units in the product. it is a spontaneous disintegration of an unstable nuclei into a more stable one.
