Write the proper charges so that an alkali metal, a noble gas and a halogen have the same electron configurations. What is the # of protons in each? # of electrons in each? How many filled energy levels do each have? Arrange them from smallest to largest IE & explain. Arrange from smallest to largest radii and explain.

    Alrighty, so you want them to have the same number of electrons. Let's use Ne as our base, since noble gasses can't become ions. It has 10 protons and 10 electrons right? Can you make a halogen ion and an alkali metal ion so that they both have 10 electrons? For ionization energy: http://www.shodor.org/chemviz/ionization/students/background.html For ionic radius, anions (negatively charged) have large radii and cations (positively charged) have small radii.
