Check all features below that you included in your Lewis structure. correct number of N and H atoms

N as the central atom

line (single bond) between N and all three H atoms

two dots (electrons) associated with the N atom

no other lines or dots

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.
