What is the daughter nucleus (nuclide) produced when Pb211 undergoes beta decay by emitting an electron? Replace each question mark with the appropriate integer or symbol.

Question

looking for the daughter nucleus (nuclide):

Answer 1

So Rebecca C.,

What chages in the nucleus of Pb211 to make an electron appear? Hint: "it" started as a neutron, at neutral charge, and something else was made at the same time so as to conserve total charge.

Double hint: the total number of nucleons is unchanged, at 211 still.
