g Give the electron configurations for the following atoms. Do not use the noble gas notation. Write out the complete electron configuration. Example: Mg 1s22s22p63s2 Element Electron configuration Ne Li N S Sc

Which of the following elements would you expect to have the lowest ionization energy value? fluorine, lithium, neon, nitrogen

Select all of the statements which are true. electrons are located in shells or orbits around the atom. electrons orbit slowly around the atom. electrons travel in one flat path around the nucleus of an atom. the valence of an atom is determined by the number of electrons in the atom's outermost shell.

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.
