Which element results if 2protons and 2neutrons with the atomic number 88 and mass number 226? Show workings

Help please

Since this is not my area of expertise, I searched Google under the key words "atomic number 88" to get these possible sources:

http://www.wordwebonline.com/en/ATOMICNUMBER88
http://www.aboutnuclear.org/view.cgi?fC=The_Atom,Structure_of_the_Atom

You could continue the search using "radium" as your key word.

I hope this helps. Thanks for asking.
