Charge on Alpha particle?

  1. Sep 1, 2009 #1
    Just wondering, why does the alpha particle which is basically just a helium atom have a 2+ charge on it when you write it although the electronic configuration of the alpha particle is exactly the same as a helium atom?

    An alpha particle is the nucleus of a helium atom without the electrons.

    The word "alpha particle" is usually used in relation to nuclear reactions, and nuclear reactions don't involve valence electrons. They're much too far away to matter.
