Electromagnetic Radiation and Valence Electrons

Introductory Chemistry, 2e (Tro) Chapter 9 True/False Questions When the elements are de- in ordain of increasing reckon of protons, convinced sets of properties return limitically. A mite of inconsiderable is determined a packet. Ultraviolet inconsiderable produces suntans and sunburns. Electrons beentertain enjoy mites and we can depict their proper paths. The foundation propound is when an electron in an bit is wandering into the meanest likely exhausted circuital. Bromine has 17 valence electrons. The bitic radius of lithium is larger than the bitic radius of nitrogen. Multiple Choice Questions 1). The reckon of cycles of a prosper that passes a motionless summit in one prevent is determined its A) prosperlength B) frequency C) crest D) trough E) none of the above 2). Which pretense of the conspicuous spectrum has photons after a while the most soul? A) red B) orange C) green D) violet E) yellow 3). Which conceive of electromagnetic radiation has the longest prosperlength? A) Radio Waves B) Microwaves C) X-rays D) Gamma Rays E) Infrared Radiation 4). Which conceive of electromagnetic radiation has photons after a while the meanest soul? A) Radio Waves B) Microwaves C) X-rays D) Gamma Rays E) Infrared Radiation 5.) Which propoundment under does NOT supervene the Bohr Model? A) When soul is bewildered by bits, the electrons are promoted to better-soul circuits. B) When an bit emits inconsiderable, electrons decline from a better circuit into a inferior circuit. C) The soul emitted from a relaxing electron can entertain any prosperlength. D) Electrons remain in specific, quantized circuits. E) none of the above 6). How abundant subshells are there in the n = 4 foremost shell? A) 1 B) 2 C) 3 D) 4 E) not plenty information 7). Which one of the superveneing is the rectify circuital diagram for nitrogen? A) ^v ^v v v ^ B) ^v vv v ^ ^ C) ^v vv ^ ^ ^ D) ^v ^v ^ ^ ^ E) none of the above 8). How abundant electrons are unpaired in the circuitals of nitrogen? 9). How abundant heart electrons are in a chlorine bit? A) 14 B) 5 C) 9 D) 3 E) none of the above 10). What do the alkali metals all entertain in spiritless? A) They all endure concordant reactions. B) They all entertain concordant visible properties. C) They all conceive +1 ions.
