Juan made the following bar graph shown to represent the relative distances of four different astronomical bodies from earth. the title of the bar graph is distance of bodies in space from earth. four bars are labeled a, b, c, and d. bar c is the shortest. bar d is about three times the size of bar c. bar a is about six times the size of bar c. bar b is about eight times the size of bar c. if d represents mars, which of the following could be represented by b and c?

The atomic radius of sodium is 186 pm and of chlorine is 100 pm. the ionic radius for na+ is 102 pm and for cl– is 181 pm. in going from na to cl in period 3, why does the atomic radius decrease while the ionic radius increases? a. the inner electrons in the sodium cation shield its valence electrons more effectively than the inner electrons in the chloride anion do. b. the inner electrons shield the valence electrons more effectively in the chlorine atom than in the chloride anion. c. the outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. d. the outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. e. monatomic ions are bigger than the atoms from which they are formed.
