A new element has been produced, called Volunteerium $($Vo$).$ This unstable isotope has$120120$ protons and$176176$ neutrons. It decays by alpha emission to a daughter nucleus.

Answer the three parts below, using three sig figs.

Part A $-$ What is the atomic mass number, AA$,$ for the daughter nucleus that results from the decay of the Volunteerium?

$292$
