A) $\frac { 1 } { 2 } m v ^ { 2 }$
B) $k \frac { Q _ { 1 } Q _ { 2 } } { r }$
C) $k \frac { r } { Q _ { 1 } Q _ { 2 } }$
D) $\text { valence } e ^ { - } - \left( \text {nonbonding } e ^ { - } + \frac { \text { bonding } e ^ { - } } { 2 } \right)$
E) $Q r$

Quizplus · Accepted Answer

The formula for formal charge is given as the difference between the valence electrons of an atom and the electrons assigned to it in the Lewis structure. In other words, it is the number of valence electrons minus the nonbonding electrons minus half the number of bonding electrons. Therefore, choice D represents the correct formula for calculating formal charge. The other options are formulas for different concepts like kinetic energy, Coulomb's law, and electric potential energy.
