A resonance structure will be insignificant if it has carbon atoms with opposite charges (C- and C ). Azulene represents an exception to this rule, because some resonance structures (with C- and C ) exhibit aromatic stabilization. Draw a resonance structure of azulene with formal charges that best explains the aromatic stabilization. Include lone pairs in your answer.

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
