Neon lights are used in many signs and commercial displays. The lights give off a unique red light. These lights work by passing an electric current through a glass tube filled with neon gas (noble gas). Neon gas produces a red color; however “neon” lights can be found in a variety of colors. Use what you know about photos and atomic structure to explain how it is possible to produce other colors of “neon” light.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

the answer is a and have a great day
