Question

what is beta decay? one neutron turns into an electron one electron turns into a neutron one neutron turns into a proton one proton turns into an electron one proton turns into a neutron one electron turns into a proton how long does it take th to turn into pa? 72 days 80 days 10 days 24 days 20 days 40 days 48 days

Explanation:

Beta - decay is a type of radioactive decay in which a neutron in an unstable nucleus transforms into a proton, an electron (beta - particle), and an antineutrino. Regarding the second question, without specifying which isotopes of Th (thorium) and Pa (protactinium) are involved, it's impossible to accurately answer the decay time. However, if we assume a common decay process like $^{234}$Th to $^{234}$Pa, the half - life of $^{234}$Th is about 24.1 days.

Answer:

One neutron turns into a proton
24 days
