One of the major advantages of the lithium-ion battery is that in comparison to dry cells and lead storage batteries, they're very lightweight. A. Write the overall cell reaction for the lead storage battery.
B. Write the overall cell reaction for the lithium-ion battery.
C. Using these two overall equations, explain why the lithium-ion battery is lighter than the lead storage battery.

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.
