Practice by predicting what would happen if the following underwent alpha decay: (2 points each)

i. Radium-226 ______+ _
ii. Plutonuim-240 ______+ _
iii. Uranium-238 ____+ _

During alpha decay, the mass number of the daughter nucleus is less than that of the parent nucleus by 4 units while the atomic number of the daughter nucleus is less than that of the parent nucleus by two units.

Hence, the daughter nucleus is found two places before the parent in the periodic table.

The alpha decay of the species shown in the question are described in the image attached to this answer.
