What is the question mark for?

jfraser · Answer

the question mark is the identity of the daughter particle once the sodium atom has decayed.

you need to know that, in nuclear reactions, $total$ atomic number must be conserved, and $total$ mass number must also be conserved. That makes this fairly straightforward

anonymous · Answer

You need to show the beta particle ( 0-1 e ) as a product.  From there using the laws of conservation of charge and conservation of mass number, you can find the atomic and mass numbers of the other product.

               2311 Na   -->    0-1 e     +     ?? X

In this case, the mass number of the product must be 23 and the atomic number must be 12.  Replace the question marks above with these numbers and replace X with the symbol for element 12.
It's a transmutation problem.
