Isotype Type of Decay

Uranium-238 Alpha

Nickel-63 Beta

Iodine-131 Beta

Radium-226 Alpha

With the help of a periodic table, predict the element that forms in each case.

I'm confused by this. Am I suppose to research each of the isotypes and find out what element they have or compare it to the elements that are in the periodic table?

**Damon**, Monday, May 19, 2014 at 3:19pmU238 for example has 92 protons and therefore 146 neutrons

It loses an alpha particle which is a helium nucleus, 2 protons and 2 neutrons

so

NOW we have an element with

92 - 2 = 90 protons

238 - 4 = 234 atomic mass ignoring E = mc^2

What has 90 protons?

Th Thorium 232 is usual isotope but we have Th234 at present
