atomic number increased by 1. mass number stays the same.

It's atomic number is one more than what it was before because it emits an electron or positron. For example:U-240 decays by beta decay to Np-240BECAUSE240 0 240 92 U ----> -1 e + 93 NpHope this shows up the way I want it to.

Grrr... ok let me re-write it.
A beta particle (when emitted) increases the atomic number by one. Sorry DrBob I was posting earlier at the same time you posted. I can't show a proper example but if you look up "decay chain" on Wikipedia it'll explain it better than I can.
