These elements appear in (*) brackets in electron configurations.
Complexes between elements from this group and halides form excimers, which can be used to make a special type of laser. An element in this group is used in a dating method with potassium-40. These elements' high effective nuclear charges give them the smallest atomic radii. These elements appear in (*) brackets in electron configurations. The synthesis of a hexa·fluoro·platinate confirmed that these elements can form compounds. Elements in this group have the highest ionization energy in each period, since elements in this group have eight valence electrons, making their electron shells full. For 10 points, name this group of inert elements like helium and neon.
