How do i determine the daughter nucleus formed when a radon-222 nucleus emits a alpha particle?

First, you figure out how many protons and neutrons Radon-222 has. Find the atomic number - that's the number of protons. Subtract that from 222 to get the number of neutrons.From that, you subtract an alpha particle - i.e., 2 protons and 2 neutrons. Use the number of protons to look up the element. Add protons and neutrons to get the isotope number.
As an alternative, since you don't really need the number of neutrons, you can just subtract 2 protons, and a total of 4 nucleids from the parent nucleus.
