Atoms of the main group elements either gain or lose electrons so they have eight electrons in the outermost energy level. In doing so, they attain a noble gas electron configuration. Match these elements with the number of electrons they gain or lose. Consult the periodic table to help answer the question. Drag each tile to the correct box.

Tiles
