Homework Help: chemistry

Can someone help me with this?

1)What new element is formed if magnesium-24 is bombarded with a neutron and then ejects a proton? Write a balanced nuclear equestion for this transmutation.

Is this beta decay? That's what I'm thinking, but I'm not sure.

It ejects a proton, so the atomic number is now 11

12Mg24 + 0n1 >>> 1 p1 + 11X24

So what is X? atomic number 11, atomic mass 24

Beta decay means a beta particle (an electron) is emitted. A proton is emitted in your problem.

Thanks guys!
