Question

3 Write the alpha decay WITH gamma emission for the following element: 92 AL 27

Answer 1

Answer:

Explanation:

In alpha decay alpha ray comes out . Apha ray is nothing but nucleus of helium atom whose atomic no  is 2 and atomic weight is 4 . Hence in alpha decay , atomic weight reduces by 4 and atomic no reduces by 2. For gamma emission , there is no change in atomic number and atomic mass.

⁹²₂₇AL ⇒ ⁸⁸₂₅X + ⁴₂He + γ

X is Manganese .
