Four possible electron configurations for a carbon atom are shown below, but only one schematic represents the correct configuration for a carbon atom in its ground state. Which one is the correct electron configuration?
Four possible electron configurations for a nitrogen atom are shown below, but only one schematic represents the correct configuration for a nitrogen atom in its ground state. Which configurations violate the Pauli exclusion principle?
State where in the periodic table these elements appear: (a) elements with the valence-shell electron configuration ns2np5 (b) elements that have three unpaired p electrons (c) an element whose valence electrons are 4s24p1 (d) the d-block elements [Section 6.9]

Label each of the following statements as true or false. c. X rays travel faster than microwaves.
Label each of the following statements as true or false. a. The frequency of radiation increases as the wavelength increases. b. Electromagnetic radiation travels through a vacuum at a constant speed, regardless of wavelength. c. Infrared light has higher frequencies than visible light. d. The glow from a fireplace, the energy within a microwave oven, and a foghorn blast are all forms of electromagnetic radiation.
