The bismuth isotope 11ea7811_3ad3_6122_bbd5_b90bdfc99b78_TB4511_11 has a mass number of 211 and atomic number 83. It undergoes beta decay where a neutron is converted into a proton, emitting an electron and an antineutrino. This results in the formation of the polonium isotope 11ea7811_3ad3_6123_bbd5_419349a76cc6_TB4511_11 with a mass number of 211 and atomic number 84.
