An alpha particle is the same as a Helium particle with a an atomic number of 2 and mass number of 4. For element 107 which is Bohrium (Bh), the balance equation is,

Bh - 266 - - > Db - 264 + alpha particle

For element 109 (Meitnerium, Mt) given that the mass number of Bohrium is 266,

Mt - 270 - - > Bh - 266 + alpha particle
