Question 20 of 31 1 Point
Which of the following best describes what happens to valence electrons in
an ionic bond?
A. Valence electrons are transferred from a nonmetal to a metal.
B. Valence electrons are shared among many atoms in a lattice.
O C. Valence electrons are transferred from a metal to a nonmetal.
D. Valence electrons are shared between two atoms.

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
