Let the Two Rows Name It

You'll learnto name a daughter nucleus by balancing nucleon number and charge rather than by recall, that a gamma emission leaves the nuclide exactly where it was, and that every beta decay has a third particle in it.

Every decay equation in this topic is settled the same way: write the nucleon number and the charge for everything on both sides, sum each row, and the daughter names itself. Twelve short steps; press Next for each one.

Before you start

What you're looking at

A decay equation with two balance rows under it: nucleon number on one, charge on the other.

The question

What is the daughter nucleus, does a gamma emission change the element, and what else comes out of a beta decay?
