INTRODUCTION TO CHEMISTRY(LL)-W/CONNECT
- Because a given element’s atoms emit only certain photons of light. only certain are occurring in those particular atoms.arrow_forwardYour text describes the probability map for an s orbital using an analogy to the earth’s atmosphere. Explain this analogy.arrow_forwardHow is the energy carried per photon of light related to the wavelength of the light? Does short—wavelength light carry more energy or less energy than long—wavelength light?arrow_forward
- What evidence do we have that energy levels in an atom are quantized? State and explain the evidence.arrow_forwardThe “Chemistry in Focus" segment Fireworks discusses some of the chemicals that give rise to the colors of fireworks. How do these colors support the existence of quantized energy levels in atoms?arrow_forwarddescribe waves in terms of frequency, wavelength, and amplitude.arrow_forward
- Although a hydrogen atom has only one electron, the hydrogen atom possesses a complete set of available orbitals. What purpose do these additional orbitals serve?arrow_forwardDetermine whether each statement that follows is true or false: a Electron energies are quantized in excited states but not in the ground state. b Line spectra of the elements are experimental evidence of the quantization of electron energies. c Energy is released as an electron passes from ground state to an excited state. d The energy of an electron may be between two quantized energy levels. e The Bohr model explanation of line spectra is still thought to be correct. f The quantum mechanical model of the atom describes orbitals in which electrons travel around the nucleus. g Orbitals are regions in which there is a high probability of finding an electron. h All energy sublevels have the same number of orbitals. i The 3p orbitals of an atom are larger than its 2p orbitals but smaller than its 4p orbitals. j At a given sublevel, the maximum number of d electrons is 5. k The halogens are found in Group 7A/17 of the periodic table. l The dot structure of the alkaline earths is X, where X is the symbol of element in the family. m Stable ions formed by alkaline earth metals are isoelectronic with noble gas atoms. n Atomic numbers 23 and 45 both belong to transition elements. o Atomic number 52, 35, and 18 are arranged in order of increasing atomic size. p Atomic number 7, 16, and 35 are all nonmetals.arrow_forwardLabel each of the properties of an electron as a particle property, a wave property, both, or neither. a mass, b de Broglie wavelength, c diffraction, d velocity, e momentum.arrow_forward
- Arrange the following three frequencies of light in order of increasing energy per photon: a.100MHzb.10MHzc.100GHzarrow_forwardGive the number of orbitals in (a) n=3(b) a 4p sublevel. (c) an f sublevel. (d) a d sublevel.arrow_forwardLight of very long wavelength strikes a photosensitive metallic surface and no electrons are ejected. Explain why increasing the intensity of this light on the metal still will not cause the photoelectric effect.arrow_forward
