Alpha emission results in the daughter nuclide with atomic number reduced by 2 units and mass number reduced by 4 units.

[tex] ^{226}_{88}Ra ----> ^{222}_{86}Rn + _{2}^{4}He [/tex]

Beta emission results in the nuclide in which the atomic number is increased by one unit and the mass number remains unchanged.

[tex] ^{222}_{86}Rn ---> ^{222}_{87}Fr +^{0}_{-1} e [/tex]

The resulting nuclide after the alpha and beta decay of Radium-226 will be Francium - 222
